<font color="blue"> IMPORTANT: Apparently you can *only* put extra lights on the B-series tractors if you get the HD alternator 'cause the stock alternator (which actually isn't an alternator at all) doesn't push enough current to power anything beyond what is already on the stock tractor.

My dealer talked me out of the $165 plus installation cost
for the HD generator.
I just bought a B7800 and asked my dealer about about putting on the HD generator because of what I had been reading about other folks (TractorByNet) recommendations.
My dealer claims I don't need a HD generator, that they install
front and rear working lights plus the flashing top of cab warning light all the time on the standard dyno system.
He said the only time he has seen a problem is when all the lights are on and the tractor is brought down to idle,
then the dyno will not keep up with the load, the lights dim and more demand is put on the battery.
Above idle the dyno can keep up with the demand of the additional lights.
I just installed my Curtis cab and 2 rear working lights are next (for snowblowing), my deal claims I will not have any problems, even at idle, with just 2 additional lights added to the system.
If I add more lights and have a problem, then I'll think about the HD generator.
The only time my tractor is at idle is when I first start it and it's warming up and just before I shut it off.
If by chance I do run my tractor at idle with all the lights on
and demand is placed on the battery, the dyno will recharge the battery once I bring it out of the idle range.
