The tachometer light bulb stopped working and now I'm unsure of rpm when motoring at night. The tach is located in what looks like a Navpod enclosure. I disassembled the enclosure and don't see how to access the bulb as the back of the tach looks to be sealed and caulked in place. Does anyone know how to access and change the bulb? How about the bulb part number and where to get one? Thanks in advance for your replies.
On my 1987 there is a twist lock type bulb holder. Get to the back of the tack, twist the holder @30 degrees, pull it out of the tach and the bulb is easily accessed. Sorry I don't have the bulb part number.
Randy see the Teleflex gauge troubleshooting document in the engine > electrical page on the TechWiki.

Thanks for the replies. The Teleflex troubleshooting guide is a great resource. I'll give it another look soon.
Well, it's been 10 months and the tach light is still out. The Teleflex troubleshooting guide has a lot of info but after reading it months ago and again today, I don't see how to change the light bulb. If anyone has done this on a MKII I'd appreciate some info on how to go about this.

I have a 2001 MKll and have changed out the light a couple of times. Once to an led bulb then back to the original because I didn't care for the led light in the tack. Wasn't any problem at all. Just follow the wires from the other lights push in and twist just don't force. FWIW May not be the bulb, may be corrosion at the light socket and bulb. I suggest some SuperLube/dielectric grease on the contacts when you reassemble.
Luck to you finding and changing the light.
Jim
As mentioned in a previous post I changed all of my engine 194 light bulbs (TOOO Hot) to red LEDs.
There should be a 90 degree twist fitting that hold the bulb. That was on a flat glass Tach instrument. maybe the domed glass tach is different.
When in doubt call Teleflex (941)907-1000 x 222

EVERYONE. As I consistently say, "
Everyone carries a camera in their pocket these days."
Randy,
see the results, especially #3. If replaceable, #4 gives you LED source and bulb number - red, amber, blue white available. If you prefer the incandescent bulb, there are silicone covers still available to "turn" them amber.

Can you see a bulb holder protruding as shown on the troubleshooting guide? If not, go back and read Google result #3.
ken
Thanks for the replies. I will take things apart and give it another try in the next couple of days. That is if the approaching tropical weather does not cause problems. Hopefully I'll have more specific questions and pics if help is still needed.
Ken, you say "can you see a bulb holder protruding as shown on the troubleshooting guide?". Can you help me zero in on where the bulb holder is shown? Is this somewhere on page 338 of the guide?

Randy that would be the diagram on 338, the bulb holder labeled, uh, "light". Just left of the terminal with the blue wire/switch labeled "panel light switch." The labeled "light" protrudes off the back of the tach case with a finger grab to twist/remove the holder.
See pics.
If yours doesn't look like that bulb holder, as I said go back and read the google result #3 re:Tflex tachs.
Randy,
Here is the back of my instrument panel. The bulb for the tachometer is not as obvious as it in the pictures Ken posted above but it is behind the black disc on my 1994 boat. Your boat is much newer so the configuration may be different again.
Dave
Do you have a replaceable bulb that you can get to under what looks like a black rubber "plug"? Or is yours one of the Teleflex tachs that have 'permanent' LED bulbs?
ken
Randy : I believe that you have the domed glass Teleflex Tach in a MKII C34.
What ever you do DON"T call Teleflex, just meander around a BLOG :sick.
A thought
Ken,
I'm standing on the boat now and I removed the instrument panel to check on the tach bulb. When I remove the black plug, I see the socket for a replaceable bulb just like the other instruments. I'll post a picture when I can.
Updated Oct 6. Picture attached.
Hey guys, issue resolved! Now that I see how this works I realize I've made it more complicated than it really is. I have a domed Teleflex tachometer. The twist socket holding the lightbulb is below the black rubber stopper. The bulbs and sockets are the same for all 4 instruments, and it seems the bulbs are soldered into the sockets. Bulbs are #194 and bulb and twist socket combinations are PC194. Superbrighleds.com has the bulb and socket combinations in a variety of colors for $5.95. I've ordered them and will replace them when they arrive next week. I will post pictures on the separate post.
Thanks to everyone for their input and help.
Sorry, but I am unable to post pics from my iPad or iPhone. If there was a way to do this let me know.
Photos should easy post from iPad and iPhone with all uploaded photos auto-resizing, if Dave Sanner's great plug-in tool is still working.
Ok, now exactly where does the lightbulb go? :shock: 8)
When I try to post photos from my iPad the below message shows up.....
An Error Has Occurred!

You cannot upload that type of file. The only allowed extensions are pdf,jpg,gif,png,txt,doc.
I have had that occur occasionally in the past but not recently. As a work around, when that occurred, I resaved the file on my desktop Imac and posted from there. Gotta love technology :?

Yah.
Apparently SmartForums wants JPG, files not JPEG. It's stupid because all you need do is rename the file extension and then SF accepts it, so it should accept that file extension in the first place. Also, in Apple's marketing strategy to be a major player in the continued dumbing down of America, it doesn't let you SEE the file names, no less change it.
Sometimes if I email a pic to myself (6s, iOS 10) it will change the extension to JPG, JPEG, or PNG -- my phone has a mind of its own what format it chooses. You might try that and then resave it to your albums.
My 6s seems to saving pix as JPG, which begs the question why is your iphone saving them as JPEG? Maybe there's a Apple aficionado out there that can shed some light on this???
David, is there a SF extension that can be plugged in to accept JPEGs, or convert them on uploading?

Randy, Is the soldered-in bulb an LED? If so I guess that's the "permanent" bulb that TF uses that I posted about below.
BTW, anyone wanting to go Amber or Blue ans stick with incandescent bulbs,

Quick update if this helps you out...
I installed two apps.
ViewEXIF - Displays ALL THE the photo file information. Seamless, just select the pic and tap the a button right in your photo collection.
Resize It - It saves back a COPY in JPG format. A VERY easy and friendly way to CROP and RESIZE a pic on your apple device. If I want to rename a JPEG --> JPG (not resize), I Just change the size by one digit (eg, 2048 pixels --> 2047) and save it. No uploading to a cloud storage that changes the name, no emailing to myself, no saving to and renaming it on my PC.

FYI for iPhone people uploading pictures: The new iOS11 introduces a new "High Efficiency" photo compression called HEIF/HVEC. When I upgraded to iOS11, it defaulted to the new file type. Go into Settings - Camera - Formats and change back to "Most Compatible" if you want to keep using the JPEG format.

I've read that the new formats takes about 1/2 the storage space, as incompatible as they are with older applications. It will take some time for PC applications to support those. The format is a standard, but not widely used (as yet.)
However the high efficiency looses significant quality... very surprising for Apple, I'd say. See comparisons:

It looks like iOS 11 forces us back to *.JPEG filenames, instead of the more universally accepted *.JPG filename. Thx, Apple.
Attached are some photos of my instruments and light bulbs. I can only upload one photo per post so as not to exceed the 200KB limit. I was unable to upload from my iPhone or iPad, even after downloading the Resize It app and resizing the photos. To upload them I saved 'em to the MacBook's desktop. This changed the photo format to .jpg.
This is a pic of the domed instruments.
Randy
So you had to reach in with a needle nose to release it?
Did you try uploading more than one pic at a time?
The uploader is **supposed to** reduce the file sizes but sometimes I've found it coughs and spits up. Other times it works perfectly. I had made Dave S aware of the problem but I don't know if he's looked into it or if there's any revolution.
ken
No, I did not know you could reach in with needle nose and release it. I pulled and disconnected the bulb from the socket's solder connection.
Yes, I did try to upload multiple photos but a message came up advising you cannot load photos totaling more than 200 KB.

Randy,
Apologies for not being clear. What I meant was, because the bulb holder was recessed into the tach (not protruding out the back as in the pix of the other panel that I posted below) did it come out w/ fingers or needed a needle nose to get at it?
I'm really surprised that the bulb was soldered in. The other tachs use the same type bulb holder but it's a push-in wedge base, not soldered in.
The only explanation I could see is an attempt to force owners to buy the bulb assembly from TF, rather than buying just a bulbs at AutoZone, etc.

Ken:
Yes, I used needle nose pliers to reach in and twist the socket to remove the socket and bulb.
