Sounds like a problem I had w/ my Chevy (which btw is
4 sale) -- when the alternator was failing there
wasn't enuf voltage to run the radio - it would cut
out,,,,next the engine stopped running 'cause the
engine computer needed at least 9.5 volts to
function...so probably you are on the right track on
the voltage drop problem - my vanagon doesn't do that
when the fan runs and the radio is on...wondering if
maybe others on the list have your problem -
One Idea i have: perhaps the cooling fan is having
bearings or other motor related problems causing it to
draw too much current??? Speculation only - I'd check
with others who have more experience with vanagons
-I've only had mine like 2 weeks :)
