My alternator light is now staying on however I am missing 2 fueses.could this be the problem?All my lights work and are not dimming at all but my blinkers quit.
The 2 fuses i am missing are the7th and 8th from the left side of the fuse box. What are the amps of the differnt color fuses? Also where is the regulator located? |

It could be the Alt, the VR, or the belt.
My engine is in pieces so I don't know where you would be able to view the belt. You should see it either on top of the engine or underneath it. You just want to check that is isn't totally loose or broken. There are some tests that can be done to isolate the VR or the Alternator once you verify the belt is in place. The ground strap is on the transmission and connects to the bottom of the floor of the trunk. The ground strap would only be a concern, if the ALT seems not to be working AND the starter won't turn fast enough. They both use the same ground strap for a return path to battery so if one is suffering the other will be too. Also, what voltage do you measure across the battery with engine off, at idle, and revving? |
