Onan won't turn over. There is a growling
dull buzzing noise when I hit the starter switch (aux)
One of the bat. teminals is corroded. (two 6 volt Bat.)
However the panel light shows that the house bat.
are green. ??
Corrosion on terminal? Bat. need replaced?
I haven't had a chance yet today to clean terminal
and put a meeter on the two bat. My engine bat. is ok.
Hope I don't need a starter.
Thanks in advance.
