Hi All. I am after a 100 amp or bigger alternator to suit the Mav TB42. I only recently replaced the original one, but with the van on the back, the thermos running and everything else, it's using more than the poor old alt can handle and it 's spat the dummy again. Does anyone know what might fit from other vehicles or new that can be easily converted. I'm sure one of you very knowledgable people has either done this or know someone who has. Looking forward to your reply. Regards, Glenn

Hi Chambo,
For what it's worth, when I had a GQ, I mounted a second alternator directly above the existing one - $30 from the wreckers. There are 2 belts on the existing alternator, one of which I extended and redirected to drive the additional unit. This meant that both belts were still driving the water pump and fan assembly, but only one belt for each of the two alternators. The original alternator simply recharged the main battery, while the second was used exclusively for the auxilliary. I did have a solenoid between the batteries just in case one alternator packed it in, but never needed to use it. You need to manufacture some mounting brackets, but it's not real difficult as there is plenty of room above the existing unit - just make sure it misses the air cleaner by getting a short or compact unit.
Mine was only 50 amps but that proved more than adequate. After I did
mine, two other club members did the same to their GQ's, each with their own version of brackets. All work very
well. Food for thought...
Cheers
Gerry
