5. Check hydraulic pressure at
1. If hydraulic pressure reads at
hydraulic fitting GE on the main
least 1800 psi (12,410 kPa),
hydraulic manifold (WP 0441,
replace electric generator (WP
Vol 3, Figure 3).
0370, Vol 2).
2. If pressure reads less than 1800
psi (12,410 kPa), replace
electric generator hydraulic
solenoid (WP 0313, Vol 2).
3. If operation functions normally,
the problem is resolved.
4. If failure persists, proceed to
6. Disconnect main wiring harness
W1 J17 from electric generator
hydraulic solenoid (WP 0451,
Vol 3, Figure 9).
7. Start BMPM engine (TM 5-3895-
385-10).
8. Turn on screed heater box (TM
5-3895-385-10).
9. Measure voltage (WP 0443, Vol 1. If voltage reads a minimum of
2) between W1 J17 pin 1 and pin
22 Volts Direct Current (VDC),
2 (WP 0451, Vol 3, Figure 9).
turn screed heater box off (TM
5-3895-385-10), turn keyless
engine switch to the OFF
position (TM 5-3895-385-10),
and replace electric generator
hydraulic solenoid (WP 0313,
Vol 2).
2. If voltage reads below 22 VDC,
turn screed heater box off (TM
5-3895-385-10), turn keyless
engine switch to the OFF
position (TM 5-3895-385-10),
and proceed to next
malfunction.
6. Fuse blown.
1. Remove generator fuse (WP
0447, Vol 3, Figure 1).
