Thread: High Output Alternator options

IMO its the constant use items that need to be considered. The winch will draw much more than what a alternator is capable of providing and will always draw from the battery anyway - but its intermittent use. LED bars use a nominal amount but Halogen spotties will draw a bit.

I run a 65AMP currently which powers what you listed plus fridge and various other items without issue - a bit of dimming on the spots when winching at night is about it.

Whatever you can get your hands on around the 100 amp mark will serve you well.

Thanks mate that sounds good. Yeah I know that you will never keep up with the winch.
100A is easy for me to get hold of. I was just wondering about getting good charge into the batteries but I guess the Bms will only draw a certain amount regardless of the size of the alternator. Am I right in assuming that?

I have always put in the disco 100amp alternator in my defenders when I have to replace the standard one.

Gives it all a bit more

I have a Transit model on mine,bolts straight up for $250. Pat

Is that out of a Ford transit pat? What amperage is that one?

Dont forget to consider uprating the charge cable between the alternator and the battery as you are nearly doubling its available capacity. Last thing you want is a bottleneck... or a fire!

Did you do the cable as well Reads? or not find it necessary?

Yeh mate,straight fit,amps,dunno,keeps both batteries charged and the fridge working. Pat

Or the Disco one (as Ali already suggested) bolts straight in, 100amps, may have to swap pulleys, depending on age of the Tdi.
About the same money from Karcraft as Pat paid for the Transit version.
