I have a problem with the alternator on my CAT 3126 engine. It sometimes starts charging as soon as I start the engine and sometimes it may not start charging until after 30 minutes of travel, maybe even longer.
I discussed this at the forum SE Rally and others here in Florida.
It appears that 12Volts supplied through the ignition switch is needed to be applied to the alternator feld to get it started. The alternator is in such a location that it is a major effort for me to test and see if that is the problem.
I checked the Winnebago electrical drawings but found no information on the wiring. The wiring is probably shown on Freightliner drawings. In the past it has been a lot of problems getting access to their drawings.
Has anybody had the same problem and what was the solution? I have been able to keep the chassis batteries charged by other methods. TNX.
