My '87 B2 with 123,000 miles seems to have a weak alternator and electrical system (battery is fine). When the revs go up a bit, the headlights get significantly brighter, and the window motors work faster etc. than when at idle.
I was looking at the 40W, 60W 100W and 140W alternators available through LMC Truck and wondering if installing a 100W alternator would kick-up my overall electrical system performance? I will be replacing my old radio/cassette unit with a new CD player in the next few weeks, but do NOT have a loud system, and no electrical extras. Also, if I installed a 100W alternator and a high voltage coil, might I expect any noticeable or measurable performance improvement? In either power or gas mileage?
Any insight appreciated. Thanks.

High Output Alternators - Any Advantage?
I would assume no. I think rebuild kits are probably just bearings and brushes, but I've never rebuilt one, so I don't know for sure. I always just get one at pull-a-part for a few bucks and forget it. It's not for sure the diode, so you would want to have it tested.
The 3G swap is popular in the EB world. You guys might want to research that a bit.

The advantage of a higher amp alternator is that you can run more accessories and the alt will stay up will the demand. Such as 100 lights, winches, stereos, etc. If you run these items that draw alot of juice they will drain your battery pretty good. I used to a big bass amp that would dim the headlights at full peak of the amp. That is when i had to up grade.
