Question about Subaru Impreza

1 Answer

Ive got a 1983 Subaru GL wagon, Automatic trans. non turbo. My problem is that the brake fluid, stop lam, and A.T. Oil temp warning lights on the dash stay on constantly. I noticed that whenand if they decide t all turn off at once, the vlotage gauge reads fine, but whenever those lights are on my voltage gauge only read arioun 8 volts. Is there a relay I should look into, Is there a possible short in one of the wires causing it to ground our cross circuit?

    I promise you it;s your alternator. I had the same issue and the guys from Ultimate Subaru Messageboard kept telling me alternator. well I checked and sure enough i had fried two out of three diodes, the diodes arnt expensive but its a tedious fix. Definetly check your ALT!! I promise! All the warning lights will subside when the alt. is swapped out.

Yes it may be the wires are shorting or its actually the problem with instrument cluster.
Also get the vehicle scanned for any error codes stored in computer this will confirm whether is short circuit issue or actual problem:------

There has to be a fuse related to the power windows, check the owners manual. it may reside in a secondary panel in the engine compartment.

SOURCE: Will not charge

you will get some funny answers from some of these "experts " The symptoms suggest to me with out much doubt that the regulator is not doing its job correctly ,consistently.Iwould take it to an AUTO ELECTRICIAN and get it tested in situ.... there is only 4 things it can be , wireing ---battery---alternator-----regulator and of those the reg. is the only one that chops and changes. it will cost little for a sparky to check the reg ,. AND I WOULD LIKE TO KNOW THE OUTCOME

SOURCE: i have a 2003 impala and its reading 5 volt

all your sensors run off the 5 volt ref. so you will have to trace your wiring harness from the pcm\ecm all the way out under the hood to locate the broken or pinched wire.

Replaced broken water pump, replaced thermostat, and the temperature gauge consistently sits just below red once it's warmed up. It never seems to go into the red if I'm idling or taking short trips, but...


hi the temp gauge should sit in the lower quarter of the gauge, it has to be a faulty water temp sensor as anything else would cause it to over heat badly

I have a 1983 subaru 1800. it has 2 electric cooling fans on the radiator. do they kick in and out depending on temp or should they run all the time?


They do not run all the time. There is a thermostatic control switch on the motor that determines when they go on and off.

Fixing automatic. Choke on a 1985 subaru gl wagon


What fails on these predominatley within the choke system is the vacuum dashpot/pulloff.This slightly opens the choke plate with vaccum present after the engine has started and gives the engine some air.The engine will be under a very rich condition without this opening.Unfortunatley this pulloff is incorporated in the carburetor top which will nesessitate replacement of the carb top portion
