Charging problems
I have a 95 SE i have charging issues, New battery, clean cables, and on the 3rd Alternator, after installing the alternator i runs find for about a hour and then the battery gauge dips back down into the red and my warning light go on and i get a beeping noise, after alternator is installed i get about 14.6 volts off the alternator, but after about a hour of driving or idling the alternator with dip down to 11 volt,but will also go back to normal again the alternator voltage acts like a rough idle in a sense with load 11 without load 14 but sometime vise versa.. then after a day goes about 9.8 - 10.7.... but then iit will spike and go up to normal... i am a little stumped I hate to take it to a Electrictan tomarrow is my day off ii can sepnd most of the day looking thru it but i would like to know if there are any "hotspots" to look in first... thanks for reading

Check and test all the battery cables, clean both ends of both cables. If you have a bad cable between the battery and the alternator it won't charge the battery.

I have a few tests you can try.

I never got around to making up a test for the positive cable.

If you've been threw multiple alts, and no change, and the battery is good, that only leaves the cables, mainly the positive cable that goes from the battery to the alt.
