alternator /charging problems

Great to hear Dave. Really looking forward to putting some miles on it. Makes me smile every time I go out into the garage!

Though it's been since April of this year I thought I'd give an update on the charging issues with my bike and what I went through, it may help some new members like myself.

Here's what I did in cronological order:

Replaced the battery
Installed new brushes
Installed a new voltage regulator/rectifier
Took all voltage and resistance measurements per the maintenance manual (to the best of my ability!) - Could not really find anything out of spec.
Inspected all the wiring and connections
Had the alternator rebuilt

After all of this, the bike was still not charging. I did some further research on the web and found that a "bad" alternator can damage a good regulator/rectifier.

Installed a new regulator/rectifier (for the second time) and this worked!!

The bike now charges at 13 volts on its voltmeter and runs perfect.

This took me way too long to figure out, but it was worth it.

I know its a lot of bread, but the alternator replacement from timscbx.com is well worth it. Its retro-fitted from a KZ, and its just bigger, so it accommodates the six just fine, allowing the battery to charge at idle instead of taking it out for a few minutes. It will fix any problem that you are having, charging-wise.

I have a similar & am pleased with the mod.... The stock alternators are fine if you use the bike often ( like Terry) but if it's a garage queen like mine, it becomes problematic.

Most people I know personally, do have the "Jung" alternator, dubbed after Stefan Jung, who was first to make them in larger quantities. Back then they were $425.- in the U.S. before the Euro's exchange rate threw a wrench into that. Stefan's latest versions had the most evolved design with a spark eroded spline in a new drive plate, thus eliminating the need for a re-welded plate and a spacer.
I don't know what Tim's is charging, but it is probably still less than the original alternator from Honda, if you could get one. I have three of those in perfect working condition on a shelf in the basement. Good place for them.
