My B&C L-60 has over 900 hours on it and is doing fine. A few more bucks, but hard to beat, IMHO. Started on a 6A and is now on my 9A. It does require a regulator.

Frank, is that measured off the avionics bus? And do you have a diode betweent he main and avionics bus?
I installed a salvaged Nippon Denso alternator from a Suzuki Samurai per this builder's site. I paid $35 for the alternator. It worked flawlessly for the 300 hours that I put on it.

...But it turned out the idiot who made the brackets (that would be me) decided to paint them...Thus providing a nice insulation layer between the alt and the engine block.

Yea that is a surprise. 14.2 volts is the min to fully charge the Odyssey SLA type bats. The 13.8 volts may be fine for a lead acid battery but not SLA. If you are not having any problems go with it. The float charge voltage (maintenance) for SLA bats is 13.6 volts. 13.8 volt will charge just not 100%. The specs on stock modern alternators is about 14.5v +/- may be a tenth or two.13.8 V...Thats what its ajusted too...A bit on the low side but apparently in spec and rock solid.

Any brush changes? I heard brushes (regardless of brand) need ocasional changing in the under 1000 hour range. It also could have to do with crusie RPM. Guys with the big flywheel pulley (9.75") verses the smaller 7.5" pulley that turns the alternator slower (and wears the brushes less).videobobk: My B&C L-60 has over 900 hours on it.
Dan: 1425+ hours on my B&C L40. Ask Gary Sobek his has in his 2000+ hour RV-6. B&C
