New too this thread having a problem with my mothers car started with the compressor motor locking up and then smoking the belt and died. Well I took the belt off and the clutch and or compressor bearing is locked up.
So I decided too put a belt on from the altenator to the crank well it runs and charges but I drove it a little then got into it going up a hill then the interior alt/battery light came on then the check engine light.
I made it to the gas station shut it off. Restarted it and I gave it a rev then the battery light went out.

But, the Tach and Fuel gauge went out also when you go over 2000-3000 rpm just guessing the car surges loss of power.

Got home put a scan on the ECU but keep coming up with ERROR CODE.

It sounds electrical in nature but, unsure Any Idea's?


Please Help!

 

Sounds like the alternator isn't charging fully. I know gauges go out at 2000-3000 rpm but, are you able to go above 2000-3000 rpm?

 

Not without the surging and loss of power. The altenator is putting out at idle read at the battery around 13.8 or 9 that seems ok to me. Like I said the fuel gauge and tach are not working everything insturment wise is working. Could be a fuse I didn't check that yet.

 

Anybody out there?

 

Seems like you were right on this because when I put the belt on it ended up stretching and hence the low charge. Now the problem is the battery light is still on. I hope it's not over charging now at idle it reads 14.5volts.I don't have the manual to check the proper voltage output at a given rpm or charging amps.

 

that is the correct voltage check if the belts loose even a little play in the belt can cause that.
