Noisy Alternator

Post by Fuzzyswing » Sun Apr 17, 2016 7:39 am

I replaced alternator on my 1988 gl1500 28k mi. On bike. Now it knocks when cold.
Put new rubber dampeners in at same time. Replaced with laelectrics 90 amp
Any help would be appreciated.

I just installed a Lactrical on my '88 a few weeks ago. It also makes noise at low rpm.
I pulled my and rotated it 180 degrees which helped with the whining but only slightly with the vibration. Heres a link where we discussed this some. Seems to be common of the high output alternators.
