24-27
If the voltage tester still does not light up:
Checking voltage supply
If the specified values are not obtained:
Checking fuel pump relay triggering - Check wiring for continuity between fuse 34 and terminal 31 (relay
position 6) using wiring diagram, correct as necessary.
- Remove fuel pump relay -J17- from the fuse relay panel, relay position
6.
- Switch ignition ON.
- Connect multimeter (Fluke 83 or equivalent) between sockets 28 (B+)
and 34, then between sockets 32 (B+) and 34.
Specified value: approx. battery positive voltage (B+)
- Check for open circuit using wiring diagram, correct as necessary.
Note:
Only by operating the starter is it possible to make the voltage tester LED
go out, otherwise it will appear dimly lit (due to low current draw). - Connect voltage tester between sockets 28 (B+) and 29.
Voltage tester must light up for approx. 1 second and then go out.
Tester must stay lit while operating starter.
