Alternator question

some starter/alternator shops will rebuild them for a ton cheaper than new one and be just as good, Davenport starter and alternator rebuilds them around here.

 

I would confirm that the voltage at the B+ terminal on the alternator is low.
Other things can cause the same symptoms.

 

How about do some troubleshooting first before loading up the parts cannon?

 

I had a truck that did the same thing. It ended up being a loose connection on the alternator, (positive charging cable).

 

Make sure all your cables are in good shape, and connections are clean and tight, does this first before throwing parts at it.

 

Walk into oreilly auto parts, they can get the right one with core return probably cheaper.

Think i walked out at 10 am next day (went in at 6 pm) for 170$ after core return on roughly same vintage truck about 2 or 3 months ago
