Found a cheap fix for a non-working ND alternator for our 1st gens this past weekend - the alt quit charging on my '92 so I pulled it off and had a look at it. Turned out that the brushes were shot. Just so happens that the replacement brush holder/set for a Honda automobile uses the same brushes! You have to un-solder the brushes out of the holder and re-solder them into your alt, but for about $25. 00, beats the heck out of buying another alt! Put the new ones in and we're back to charging! Honda part number: 31105-PZ1-003.
