Main Message Board / engine room sound insulation

Last post by Pete G - Today at 07:10:22 AM

Any recommendations on replacement foam?  As part of my engine room refresh, I removed the originals - the PO ran the engine without a dipstick for a while.  :-\ 

I see some spendy foam panels at West Marine, wondering if there's a Home Depot option.

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.

The switch is between the two terminals.
Not the terminals to ground. 
Recheck the switch.

no tachometer reading, no fuel gauge reading and the temperature gauge reads ~ 200 F after engine running for 1 minute.

I presume with the items still disconnected as you described below?

I can second the above on my 1991 mk1.5. I doubt they would have changed that detail from one to the other.

disconnect 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.

Updated, I guess it was reposted and link changed
 Video is about LiFePo4 batteries

Mark- this is a "bad link" (not working) please fix or remove. Also what is the subject of the video?

I 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.

To 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 filed FAILED and replace it -- if not we'll dig deeper.

Should I do this?

@d

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.

I 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?

is it the oil switch or the temp switch that is alarming?

did he {mechanc] use the wiring schematic to understand why it is alarming?

I missed it if you previously answered this.

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!
