Here's what I found. Checked all wiring,
connections and grounding. Still only showed just
a slight charge even though battery was near
complete discharge. I could ground the FLD
terminal and effect significant charging. Took
cover off VR and noticed a constant arcing between
the contacts on the FLD relay (if that's the
proper name for it). I could manually close the
contacts and get a good proper charge. I ever so
slightly increased the spring tension that allowed
good contact closure and eliminated the arcing.
Battery was near completely charged in about 20
min. of mowing. I was hesitant in making any
internal adjustments but hopefully problem is
resolved. Thanks for all help and suggestions.
Any further comments welcomed.
 
Good, you found the problem. That relay should arc a bit, especially as the battery nears full charge,
Set that spring tension so the voltage at the battery posts is 6.6- 7 Volts for a 6V system, and 13.5 -14.5 volts for a 12V system.

Check the final adjustment with a fully charged battery and the regulator cover in place. The regulator cover slightly affects the voltage setting. Let everything run for atleast 10 minutes before attempting the final voltage adjustment.
If you get it right, you will have mastered an almost dead skill. :)
 
Thanks Jon. I suspected there was probably be some finer tuning involved. Now that I know what to do I'll keep tweaking it. Thanks again.
