Thanks for the reply. Here’s more of the story. Last night I checked all the grounds and they are good. There was a constant hot wire run to the deck and an extra cig lighter that I got fixed. Still having a problem with the “accessory” 12v wire that turns on the stereo and powers the tach and voltmeter. I’ll attach a few pictures of what I’m looking at. Both the gauges and the accessory power to the deck are spliced into a red/green wire that goes into a loom, back behind the stereo, then to a bigger loom, behind the air ducting behind the steering wheel. I don’t know where it all goes from there, without tearing apart the whole dash. Anyone know anything about the red/green wire and where I may be able to track down the other end of it? Should I not mess with the red/green wire and find another 12v switched wire and just run everything from that with a clean wire?
First picture is the red/green wire that splices to a red wire that powers the tach and voltmeter. You can also see the extra cig lighter here.
Second picture is the red/green wire spliced into a red wire that runs to the stereo “accessory” circuit.
Third picture is the general setup. Don't think the tach is on here, it's stuck there, without power.
