TEST 15:- LOW FUEL
The motor home engine and the alt­
ernator engine should "share” the
vehicle fuel tank, through a dual
fuel pickup tube arrangement. See
illustration at right. To prevent
the alternator from depleting the
fuel tank, the alternator fuel
pickup tube is usually several in­
ches shorter than the vehicle eng­
ine tube. Thus, the alternator may
be "out-of-gas" while the vehicle
engine has a sufficient fuel supply
Make sure the alternator fuel supply line is NOT connected into the ve­
hicle engine fuel supply line. If the vehicle engine is running, the
alternator engine may be starved of fuel. When the vehicle engine is
not running, the alternator may drain the vehicle engine fuel line (and
even the vehicle engine carburetor). The latter will result in hard
starting of the vehicle engine.
TEST 16:-NO FUEL FLOW
Disconnect fuel line at Carburetor
inlet fitting. Place open end of
fuel line into a suitable contain­
er, then crank engine. Fuel should
pump from open end of fuel line.
If little or no fuel comes from
fuel line, check in-line filter for
clogging. Replace fuel line and fi­
lter, if filter is clogged. __ _ ---- CARBURETOR

Fuse Puller Tab for easy removal.
Remove the Fuse from the Printed
Circuit Board and test in same
manner as 15 Amp Fuse (Test 1). If
Fuse is defective, replace.
