alternator

Postby rogerg55 » Sat Aug 23, 2014 12:57 pm



OK got my Alternator off. I got 100% continuity between rings on the stator. 100%
Continuity on the fields which i think is correct. 100% (a-b)(b-c)(a-c)
Lots of dust but brushes are not stuck. So regulator? if I cut across this point and replace regulator and solder back. Is thaPt OK?.
88 gl1500 lr140+707 are hard to find. I find a lots of lr140-708. Bolt hole is 6 MM
Mine is 8.9 MM buy an drill it out?
Or last resort someone has upgraded an would like to sell a good used one?
P.S 300 mi. Monday no alternator. My wife followed me ride 50-75 miles recharge. Etc etc etc
Thanks in advance

You checked for continuity, but did you also check to see that they weren't shorting to ground ???

The dust can be from the brushes and can cause conductivity were it is not desired... If all test show good (also checking for shorts to ground) then possibly a good cleaning and new set of brushes will return it to good service... If it does not then a regulator would be my next tests...

Cut the rectifier plate :shock: NO

If the rotor and stator Ohm out correctly the regulator/rectifier gets replaced as a unit.

As long as your rotor Ohms OK you can use your front housing on a different stator/rear for the correct bolt/alignment issue.

You do know that later model GL1500 alternators will fit up and work with your '88 right?

It's been a while since I replaced one in an '88 pr '89 but I recall that the upper and lower mounting points on the engine are the same for all GL1500's. I believe the later alternator mounting ear has a larger casting so they will fit all GL1500's. I'm not 100% sure which mount hole but I know the later alternators do fit.

Thanks MikeB, I found an 85 amp LACTRICAL alternator.I have a new wet cell battery never put acid in it. What's your opinion on these? Trying to keep cost to a minimum.
Maybe after this question I'll be good to go. THANKS to all who've helped me the last few days.

The only ting I know of the LACTRICAL is what I have read here. Do a search of the Tech Forum using LACTRICAL as your search word.

As to batteries, I will only use an AGM (Absorbed Glass Mat) battery.
