2006 IC Conventional, T444E; amp guage started "wavering". Can go from -50amps to +75 amps. Volts are steady @+-14.0. This occurs with or without a load. Bus continues to start everyday with no problem. Any suggestions?
If its an 06, it doesn't have a T-444-E.... Its got the VT365. We had problems with the voltage on our 2005 CEs with that engine, they replaced the alternator, I believe. Ours are cheap and don't have the AMP gauge, but the volt gauge used "float" around.
I had problems with my IC CE300 06 and up amp gauges, as long as the charging system cks good. ask your dealer about changing the update rate in the body esc. if i remember correctly the amp gauges are usually set at the top of the range from factory (which is the fastest update rate) and seem to be alright for the first year or so then will start bouncing all over the place. they slowed the rate down to 10 or less and all is well so far gauge reads normal and doesn't freak drivers out. you can find this setting in diamond logic builder program if you have it, but apparently you need the dealer software to change.
