Last post by dclintonbaker - Today at 07:13:07 PMdisconnect the two wires from the oil pressure switch..the alarm continues.
disconnect the temperature switch and the sender from the thermostat housing..alarm continues.
Testing the new oil pressure switch..engine stopped, open circuit from both tabs to engine ground.
" " engine running, open circuit from both tabs to ground.
New information..now I have no tachometer reading, no fuel gauge reading and the temperature gauge reads ~ 200 F after engine running for 1 minute.

Main Message Board / Re: replacing transducers and ...
Last post by Pete G - Today at 06:59:29 AMI had both a 2" and a 1 7/8" hole saw, but the smaller one isn't small enough to fit inside the larger. If the hole was 1 3/4", I think this would have worked. However, the "drops" from the 2" hole saw are exactly 1 7/8" in diameter. I cut a couple of donuts from a 2/4 and screwed them onto the mandrel. This worked perfectly, drilling in reverse.

Last post by KWKloeber - Yesterday at 07:23:24 PMQuote from: dclintonbaker on Yesterday at 05:00:12 PMTo check the switch, remove the 2 wires to the switch, short the female terminals together (for a good connection I suggest a jumper wire w/ 2 male quick connect terminals, rather than taping terminals together.) If your alarm problems go away, the switch has@dfiledFAILED and replace it -- if not we'll dig deeper.
Should I do this?
That's not the OEM Wb wiring that I have seen when I replaced a "B" harness. So from afar it might be difficult to tell what you have there or if the PO modified it.
Wb typically installs harnesses before painting the engine so all the wiring is Ice Blue color. Even if not, the OEM wiring had one terminal crimped with two wires (one being red/white stripe) and the other terminal had one wire. And those are not Wb terminals or Wb crimps.
Quote from: KWKloeber on May 03, 2024, 01:05:52 PMI went thru the wiring on the forum and checking the voltages at different points with another owner. If you can't locate that old post with a search I may be able to find it.Did you look for that?
Quote from: KWKloeber on May 03, 2024, 01:05:52 PMis it the oil switch or the temp switch that is alarming?I missed it if you previously answered this.
did he {mechanc] use the wiring schematic to understand why it is alarming?
Disconnect the two wires.
See what the alarm does.
Verify whether the oil switch is open or closed (w/ engine off and running) using your ohm or continuity setting on your multimeter.
Report back!

Last post by dclintonbaker - Yesterday at 05:00:12 PMInteresting post from Breakin Away about importance of installing the correct switch.
Here's another attempt at a picture of the oil pressure switch..for what it's worth.

Last post by Dave Spencer - Yesterday at 03:55:08 PMHi Mark,
I don't have a Mk II but I've attached a picture of the mounting bolts from my Mk1.5. There is definitely a tapped backing plate embedded in the fibreglass. Your boat may be different but a backing plate makes sense from a manufacturing point of view since installing the swim ladder brackets if it was secured with nuts would definitely be a two person job.
The attached picture was taken when I had the rear water tank removed and was renewing the bilge pump hose that discharges at the centreline under the swim ladder on my Mk 1.5.
Good luck with whatever you're doing.

Last post by MarknCat - Yesterday at 01:15:12 PMHi everyone, anyone pull their ladder mounts off? Is there a backing plate molded in with threads or is there nuts under there?
Thanks
Mark
