basic functions such as stuck contacts can sometimes restore operation just by a simple cleaning of the relay contacts. The ones I have "restored" generally fall within a range the manufacturer considers acceptable If I clean the relay contacts and see the ammeter surge to +10 and taper off to 3 or 4 after a minute or two - I feel the reg is doing its job. I really don't worry if I can squeeze exactly 15 amps thru the reg, just so i can restart the tractor after I shut it off.
If I can measure between 13.5 and 14.5 on the battery during recharge, I don't try to tweek it any further. I just enjoy the 6 months or more life I just breathed back into the reg and start a search for a replacement.
If I didn't have to buy a minimum order of 25,000 relay contacts from overseas suppliers, I would do the contact replacements.
