Hello ... we don't get the heat most have down south, I always enjoy the chase to solve issues, for cooling a Toyota truck and cab that never came with the AC unit.
Where an older model ((90) 22r (re) it never had the compressor for ac but had a blower for pollution control, I purchased a second alternator from the junk yard and it fit nicely into where the air compressor lived to blow air to exhaust system. I then found
the belt that fit my now mounted second alternator to the engine pulley and wired it in parallel with the stock alternator, such that each alternator worked as one unit, one alternator was 60 amp, the other was 90 amp, so had 150 amp supply when needed, it
still works great 30 years later, but at the time it ran a inverter that ran a ac unit in my back truck window, this was not in my Toy rv, but my Toyota 90 truck. Anyway, for my AC unit in my 87 Seabreeze I have a generator on the back bumper, 2000w inverter,
will run my roof ac when we park or travel, I guess. The point is a second alternator worked out very well and gave me lots of electrical power. I found the dual alternators acted as one due to been wired together in parallel when the demand wanted power.
Important to instal heavy load wire of the second alternator which went to the battery with the original.? Just a thought.? ... Bruce in Canada
