lost all gauges

My guess is that this will be a very quick fix.  You're going to find either a blown fuse, a bad ground or a bad power connection.

On mine, the gauges and the brake lights are on the same fuse. Just FYI. So it's good to snap a new one in before driving home at night, if possible.

Well finally found the problem...after messing with the wiring for about a day, checking for loose grounds and connections, checking the fuses etc 3x...duh! still couldn't get any of the gauges to function. Finally yesterday, as I was about to light the dynamite under the car...LOL, I pulled the fuse on the fuse block labeled 'gauges' and replaced it...lo and behold the gauges worked...

Don't know why because the the original fuse still looked good, did not appear blown, ohms out even??? put in a brand new fuse and everything came back on. I sprayed some electronic cleaner on the the fuse block a few times so it may have been just a bit of corrosion on the connections and it possibly the cleaner finally broke the corrosion down??.

 

This car had spent its entire life near the CA ocean before I got it and there was some corrosion, minor, on various metal and electrical surfaces and I do know electrics and electronics can really attract it. Earlier this winter when I was sorting out some electrical issues I did find some corrosion on the fittings for the headlights and tailights...so that may have been the issue here...just some built up corrosion...knock on wood...

 

Anyway everything is functioning again Troy was right, pretty easy fix once it was sorted out.

Use your OHM meter and check the "resistance" of that fuse.....   I had one on my first Spyder, that came installed, that read 40 ohms and had a 20amp rating...It should have metered around 6.5 ohm......   wondered why the high beams didn't work even though the dimmer relay did....  And voltage at the socket too.....  This was a Buss/Little Fuse glass tube type...

I had the same problem with a little bus VW-type fuse. You can look right at it, and see it's fine. Replaced it and lo and behold.
