Replacing gauges

Postby Hit&Run » Tue Jun 11, 2019 1:34 pm

Hello, I have a 2001 28’ Martinique that I just replaced all the gauges on. After finishing I turned the key one click and no beeping sound and gauges didn’t move. After going over all the wiring (and seeming correct) I cranked the motor which now cranks but doesn’t start. I’m wondering if anyone else had this prob after changing gauges. Original gauges were all analog except the Hr meter on the RPM was digital. The new RPM gauge doesn’t have an hr meter and I’m wondering if that’s inter fearing with the Sea-Fire?? Faria gauges replaced with new Faria. Ty

Wow That's a good one, I've replaced some gauges in my life but never had a problem like that. Welcome aboard by the way. I'd start by checking breakers and fused links in the engine control system good luck
The older I get the better I used to be!

I think power to ignition is fused before the ignition switch. Since the engine cranks then power is getting to the switch. The run position sends power both to the engine and the instrument panel. I think the fiddling around behind the instrument panel has loosened or pulled off wires at the ignition switch. The connections may look ok but there may be corrosion. So wiggle behind the ignition switch and see if the gauges come to life. You may need a 12 volt tester to tell how far power is getting. Make up a jumper cable with alligator clips on either end. To make it easier to probe, connect the black probe on the tester to the jumper cable and the other end to a known ground, leaving hands free to probe.
There may also be a wiring harness plug behind the instrument panel that you inadvertently loosened.
Finally, you may have touched a live wire to ground blowing a fuse or breaker somewhere. I think the problem is behind the instrument panel as that is the only place you have disturbed. The 12 volt tester will solve this for you.
