GQ Alternator

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

plenty on it.

I had a Bosch unit made to do the job but its 85amp which is still better than the original 55. Any good auto sparky should be able to make one up for you.

85 amp alt from a VL Commoodore will fit, after a pulley swap, you could fit a 110 amp/hr from a tojo if your really desperate.

Look at this mob, very competitive and great range, incl oversize for your Mav.

Used them for a new alternator a couple of years ago, very happy.

Thanks everyone for your input. I have also found out that the alternator off the Nissan Maxima will fit and it comes in 95 and 110 amp. Cheers, Glenn
