Wanting to fit an extra Alternater to the Truck " 2003 Nissan 4.8 Petrol Patrol can see how it can be done but before i go ahead throught i would post and see if anyone else has done the same.
There is enough room if i move the water bottle for the window washers and have a holding bracket made up then run the belf just in front of the original one.
Any Ideas anyone

If the prices for the petrol are any where near what a 3.0 litre costs you might think again.
Absolute rip off these patrols are for parts.

It's interesting, a front mudguard for a new Commodore is $195.00 and a front mudguard for a Honda Accord is $700.00. buy local and get cheap parts. Pity they dont make a decent 4x4 here!!

Have not tried it. I would want to check out what effect it would have on the regulator and diodes with an auto electrician first.

Have you thought about replacing the original alternater with a larger alternater with higher output... If the leads were rewired you could use one out of a different vehicle make. Just cut the plugs off and solder the corresponding wires together.

Dan 1 gets my money why another alternator Bosch alternators 100amp have been fitted to Cummins diesel truck engines replacing the notoriously expensive Delco .There wouldnt be too many old 350 400 big cam Cummins getting about with original alternators. Many outback livestock carriers had an alternator out of Holden V8s as a spare neath seat just drill out the mount hole to 1/2 carry a long bolt to suit. Built in regs these days make it a breeze.

Hmmmm gets real tricky putting two alternators on the one bus (jargon for electrical circuit) not that I know much about these things. From experience with aircraft more trouble than it is worth. Need some sort of balance circuit to keep the level of the two alternators the same. Try an auto lecky, but yeah well, good luck! :) Let us know how you go...

If you are just trying to increase your charging power I changed over my alternator on my GQ from the original to a bosh high output, it was a rebuild from an auto electrician but simply it was a holden alternator with the correct drive pulley fitted and I had no modifications to make to the vehicle, the only thing that I did do how ever was to increase the size of the cable from the alternator to the battery to avoid overloading the original wiring. The cost of the alternator was $100

I have two alternators on my GQ diesel - the vacuum pump on the back of the alternator makes it close to impossible to find a high output replacement.

While I had problems initially, this was rectified by running the dual batteries as two seperate systems - one alternator dedicated to each battery.

I was charged about $150 for the second alternator bracket - all up, I was charged close to $600 by a Melbourne 4 x 4 specialist using a second hand 85amp alternator. Dual batteries were already fitted to the vehicle.
