I have searched the files for about 45 minutes looking for a write up on installing the 50 amp in place of the 32 amp. I can't find one. Can someone please give me a rundown on the steps involved.

I am running 2 sets of running lights and heated clothing now on my early '93 Klt. While in WI a month ago, I drained the battery using the two sets of auxillary lights and the headlight. I had to jump the bike from my friend's Victory. That was embarassing. Embarassed

I picked up a 50 amp alternator and am ready to install. Will this also fit on a K75c? If yes, I will need a second one. Thanks. Embarassed Embarassed

This is from memory so wait for someone else to verify.

Run a large battery cable from the large terminal on the alternator to the + battery terminal. Take the blue wire from the current alternator connector, put a ring terminal on it and connect it to the small terminal on the alternator.

Yes, it's possible on a K75. MY project K75S has one.

There's a couple of R1100 alternators on ebay for $90 buy it now - good price(Same alternator - you need toreplace the pulley wheel with a K bike "cup." I did that on my LT.)

I have from a bike with only 8000 miles for sale for $175.

Dave,
You need the driven cup from the 50A unit to mate it correctly with your early drive dog. The cup has changed but the drive dog has not.
There was a very complete write-up on this forum until all the old posts were lost about a month ago. Sad

Mick

Mick,




Any idea who wrote up the install notes?
