Off to the dealership to start to work on this alternator (potential) issue.
Good luck.
But it is not a "potential" alternator issue.
The max. charging voltage should be about 14.5 and it should not even stay at that for very long.
The regulator is built into the alternator these days so unless there is a wire pinched and shorted out somewhere.....it just about has to be the alternator.
Note: Having said all that......mine runs at about 14.3 ALL the time. That concerns me a little but so far no problems.
Ha ha...thanks for the well wishes.
It went about as I figured it would: nowhere really. The specs they looked up (same place they would for trouble shooting) said the target charging output in "charge mode" is 13.9-15.5, and that depends on state of charge and estimated batt temp. They didn't seem to think they could get any test to indicate replacement is needed. What I could not seem to get accross is that it does not seem that it should be staying at 15+ volts all the time. I have not come accross any battery type so far that would want 15+ volts in perpetuity. I very well could be wrong about it all, however...lol.
Goint to call a different dealership tomorrow that I know does alot of work on larger fleet-type chassis such as this Express 4500.
Bobndot: thanks for the idea and links for the extra battery mount. Had not thought of that. Could allow for some bigger batteries.
