Is the 40 amp alternator output the save for the BX2350/60 and BX1850/60? Seems it wouls be. I ask because I'm in the process of wiring up two 55 watt work lights and I'm assuming I can run these off the stock alternator, which I though was 40 amps.
I have BX24 and i am including a pic of my alternator. I found a pic on this website that shows the old dynamo alternator that looks smaller and has solid casing. perhaps you could compare yours and make an educated guess.
Thanks, I'll have a look as soon as I can get out to the shed. About 14*F here and icy. I'll be waiting for some warmer weather to finish the install (have the wires run and the switch installed) anyway. I'm pretty sure all the BX's are the same as far as the stock alternator but now I know what that dyno looks like so I'll know for sure.
