Make sure the red wire is connected to
the positive battery post and the black
wire is connected to the negative. If
the fuse still blows, contact your
STANDARD HORIZON Dealer.
Reroute the DC power cables away
from the engine. Add noise
suppressor on power cable. Change
to resistive spark plug wires and/or
add an alternator whine filter.
