hi everyone
i have an 88 RX7 NA and my rpm,battery and gas gauges suddenly stopped working. can anyone please help on what could be the issue
thank you

note:
oil temperature gauge not working from before so not my main concern
speedometer works

 

The Room fuse powers all gauges except for the speedometer so check that fuses condition.

 

ok but which dept in the fuse box will be ??

 

The cover to the fuse box explains where each fuse goes. Did you lose the cover? There is a pic in the FAQ section for the S4, but the S5 is very similar and the S5 service manual also has a diagram.

 

you could also use a test light and manually check all fuses takes about 2 mins tops.

 

oil sender unit for the oil pressure! even though it's not your main concern :p

 

thanks everyone it was the meter fuse and got it replaced.
