Some of you may remember that I have benn searching for an answer to why my TrueCharge has been kicking offline sometimes.
I'll try the following suggestion form Duane this weekend and let you all know how it works out.
Absolutely no problem disconnecting the Voltage Regulator (Charger) on
the Onan.
The Flywheel Alternator is the source of voltage that is used by the
Voltage Regulator to provide a small output for charging an Onan
dedicated (Early GMCs had small Motor Cycle type battery for starting the
Onan & were charged only by the Onan Voltage Regulator). GM quickly
recognized that House Battery could located near the Onan & serve dual
purposes. However., the Voltage regulator was never removed from the
Onan (no longer required since the Dual purpose battery was charge by the
Engine alternator while driving & by the AC to DC converter when shore
power is available).
The Flywheel Alternator is required as a feedback signal to the Onan
Control Board to identify that the Onan is running & the starter is
automatically disconnected. Also for shut down function to remove
Ignition power.
I have repaired many Onans control problems by disconnecting the wires
(typ. 3 wires) going to the Voltage Regulator (faulty VR that are loading
down the Flywheel Alternator output voltage). Remove the wires & tape
up. Maintain the common connection if exist (typ. 2 wires together on
one terminal).
We should all remove the VR wires as preventative maintenance !!!
