Stay running problem

[Gregory OConnor]

Your issues with the Genset starter could???? be a clue to electrical
issues with the Detroit DDEC. The Genset starters get burnt up by
trying to start it with low batteries and or cranking too long to
bring fuel up to the gen from the tank. My genset fuel drifts back
to the tank if it sits un used for more than 3 days. The electric
fuel pump runs while you are glowing plugs with the momentary switch.
You can also run just the fuel pump by jumping the positive lead. If
the batteries are low, I move the tray out then hook a battery jump
pack positive clamp on the big wire lug to the starter and the
negative jump pack clamp is hooked up to the Genset frame. I glow
the plugs regardless of the outside temp (count to 20) and it is an
effortless start. I keep the Pepboys jump pack plugged in to a
inverter 110 outlet in the bay (it has a builtin automatic charger)


The following is what I understand about Aux. Battery switch and
charging????????????
The genset will not charge the Detroit start batteries unless you
turn the dash AUX. Battery switch to the position that turns on the
indicator light. You will note that while the Detroit is running
this light comes on automatic and the big alternators on the Detroit
are charging both battery banks. When the bus is at rest (no Genset
or Detroit running) and you are using the inverter it is best to keep
the Aux battery switch centered (off). If you inverter camp with Aux
Battery light on , both sets of batteries are being depleted. When my
bus is parked for storage periods I keep it plugged in and the Aux
light off/ centered. If the starter bank of batteries read low
before a trip I hold the Aux momentary button while I start the
Detroit.
