SP36 Alternator Schematic - djmahoney3 - 08-12-2009 02:34

Does anyone have an alternator schematic for this unit? The alternator is
supposedly putting out a charge, but it isn't charging the batteries.

Thanks,

I assume you checked the voltage at the isolater located in the coach battery
compartment. Mine went bad and had to be replaced.

Hi  Bob    Did you ever figure out how to keep your engine compartment any cooler & your fan from coming on as often?

Hi Don.
Hope you are having a good time in SD.
I found, as mentioned in previous posting, that my oil cooler had leaked oil
into the cooling system. A big mess. I still have the sooling system
conditioner/cleaner in the coach so I don't know if the heating problen causing
the frequent cycling of the fan is solved or not. I expect not. I had a long
discussion with the folks at Caterpillar who installed both the new engine and
the new radiator. The solution has not been found in spite of the installation
of a 16" electric thermostat controlled fan to help the mechanical one. It
still cycles more often than the old rad with old engine. This is on-going but
I am almost certain now that the rad is the culprit. I will let you know when
the problem is solved.
Have a safe trip.

The radiator shrouding is important to match up and reinstall properly plus fan
speed and clutch performance is important too. If I had a 3208 I would
definitely find a two speed aftermarket fan that would work. It may cycle more
often becaue the t stat was shadetree engineered????
In an old 3208 dumptruck I would always try and manually engage my fan at low
rpm when the temp gauge clued me of a soon to clutch-up event. I didnt want the
belt and bearing to experience a 2800 rpm abrupt torque-kick. with the two
speed you could shade-tree engineer a t stat to turn it on at a lower temp and
may never have it go to high speed??.
I have this fan clutch on a 92 N-14. I think this will solve many 3208 issues.
