I have a Winnebago Journey on a Freightliner XC chassis and Cat C7 with a rear radiator. The engine access is only possible from under the bed, and the the access is VERY restricted.
My alternator has not caused any problems in the 6000 miles I have owned and driven it, but it constantly overcharges. After startup, the voltage is typically 15.3 volts. On the road the voltage fluctuates between 14.6 and 15.1 volts. I'm thinking I should replace the alternator before I have a breakdown.
Can anyone offer any insight as to how difficult this job is going to be?
Suggest you verify with a good digital voltmeter, before doing anything else and should be able to see the alternator's output and any fluctuations from the 12vdc outlet in the dash. Just make sure it's on the chassis batteries. I would use a 12vdc plug with a pigtail for connecting the meter and where I could monitor it for awhile.
