Alternator Replacement

[Leroy Eckert]

Good deal. You are probably ok now . Mine will vary from 100 to 150 amps
depending on the load. I have learned not to get excited about it.

My alternator replacement job is done, I'm happy to say.

For memory refreshment, I had Alternator 1 with zero output, and Alternator 2
with max 50-amps and unable to maintain voltage with headlights on.

Replacing the top-front one (under the bed) was easy. That one was a 130-amp
Prestolite. After replacement, and with the power cables removed from the back
one, the engine was started and showed 100 amps on Alternator 1 at idle, zero on
Alternator 2. Voltage was above 13.5 and amps dropped quickly as the start drop
was replaced, even with the headlights on.

Replacing the back alternator was not easy at all. It sits under the A/C pump,
so I tried to drop it out the bottom, but there just wasn't room to make it. The
way the A/C pump is bracketed it was a B***h to remove, and similar to replace,
but I eventually got it done. The removed alternator has no apparent markings
anywhere, so I don't know what it was or its rating.

Running with the two new Leece-Neville 160-amp alternators the output after
startup is still 100 amps, shared equally between the two. I guess that makes
sense, but I had thought it would be higher. I wish I had a way to draw down the
batteries and still have enough to start the engine, so I could see if it would
show a higher charge rate.

Overall it was an interesting learning experience. I also replaced the belts
on Alternator 1, which showed some wear, but the others - alternator 2 and the
A/C pump - looked like new so I left them.
