lost trim function after testing coil

[kingsfisherman]

Hello All,

I was doing some ignition testing and after doing the test in step 9 (see pic) I lost the trim function and the gauge is pegged, what could have happened? Note: I do have connection between the switch and the limiter.

update: I tried using the override switch and the drive comes up but won't go down. I'm sure it was in the right range to go up or down prior to the testing. So for some reason I only have trim up when I use the override switch.

update #2 was able to operate trim in both up and down while using the override switch.

update #3
found the Black wire broke at the backside of the trim limiter connector to the sending unit, can I cut the connector out and splice these wires? I know the sending unit uses resistance to tell the limiter the position of the drive, will splicing the wires affect that function?

update#4
went ahead and cut the black wire at the sending unit connectors side and spliced it it the limiters black wire. will test it soon.

well I got the trim to start working again after splicing the broken black wire but the trim gauge is still pegged, I did try to adjust the sending unit to the 11 ohms prior to finding the broke wire, so I will revisit the sending unit setting tomorrow, thanks for following!

There is a trim limiter module in these....I believe. Not sure when they started using these or even if they still do but you may be able to remove the darn thing and just plug in the trim wire plugs together after removing the module.

Seems dumb to have these as often as these trim senders go out!

I installed the trim limiter so I didn't have to guess if I was in the "safe zone" when trimming the drive. Usually the promblems I've had stem from wire corrosion and bad connections
