HEllo 1st off i got a 1988 rx7 gxl! none of my gauges work tach,spedo,oil , none! lights up and turn signals work. Guages are fully connected inthe back so what could it b? again NONE of the gauges work just light up! plz need some help my rotary specialists!

 

i checked the fuses they were good ill double check tommorow

 

Are you certain the 7.5 amp meter fuse is good? Checking by continuity is the best way to determine if it is good.

 

does anyone have a fuse panel and block indetification for the 1988 rx7 i dnt have mine so idk which fuse goes where and mayb i missing the fuse to the cluster?

 

 

ok thanks! will check! so the 7.5 room is the one for the cluster?

 

Meter fuse!

 

ok so turns out the meter fuse had 10 fuse so i switched it to the 7.5 and wha la my cluster works complely or so i think! So now that it works i see that only my tachometer,oil pressure,fuel,and temp meter are the only ones working! My speedo or volt meter DO NOT WORK! any help on whatt could b making them not work? pleaze rx7 club u guys been great help getting my beast running just a few minor things left so any help on how to fix speedo and volt meter!

 

speedo is a mechanical gauge that has a flex line that goes to the speedo gear on the transmission. it likely wasn't plugged in correctly or at all into the back of the cluster.

the voltmeter works off the signal wire from the back of the alternator and runs into the ECU at the LF kick panel inside the car, start by checking the 2 pin connector off the back of the alternator and be sure it is plugged in and the wires are in one piece.

 

Clean the screw contacts in the back of the gauge.

 

havent cleaned the back of the guages yet... but checked the alterantor its fully plugged in! Is there anything else that can keep my volt meter from working?

 

could my mods mess anything up?MOds are egr block, no ps, and no ac?

 

They should be messing anything up so long as you haven't knocked anything loose in the process.

 

Try cleaning the screw contacts to the volt gauge. You might be surprised.

 

ok hopefully tommorow or for sure this weekend ill take my cluster apart and fully clean it!!!!! ANything special to clean the contacts?

 

Contact cleaner perhaps.

 

ok update my volt meter works now but my speedo still dont work. I unplugged the speedo sensor from the tranny cleaned it put it back in. Speedo still dont work so hoping when i take apart my cluster this weekend and clean the contacts itll work!!
