Weird Issue


Recommended Posts

Turned on my EA-82 wagon and the rpms shot to around 3k,

I let off the gas and it would go to idle and shoot back up

on its own lol. After it warmed up it went back to normal,

however my voltage stayed really high something like 16v WTH?

 

possibly a vacuum leak. I dunno about the high voltage though

I'm not sure about the weird reving. 16V is too high. Check with a multimeter. back of alternator and battery. They normally should be close. If there is more than some tenths of a volt, check the electrical connections from the alternator to the battery. Should be the big wire on the back with a nut, not the little plug on ones. Looking for high resistance / burned contacts. Possibly one of the fusable links? (check the schematic)

The voltage COULD be just the RPM revs, but the needle movement shoudn't be abrupt - it should be slow - if you have abrupt moves, you gotta look for shorts somewhere.

 

If it's gone after you got the revs fixed ... then thats probably it.

Well, as stated before, did you notice any difference in voltage after the

fusible link change?

If it fixes it, then there you go!

If not check your voltage regulator, as stated before.

If your voltage regulator is shot, then you'll have to replace it.

I'm not sure, but I think that's onboard the alternator, and if it is it'll

probably be easier (and cheaper :rolleyes: ) to replace the alternator.
