No power to starter relay?...

Complete ground up rebuild. Swapped in aw4 from ax15. No neutral safety switch no hook up, was manual trans before. Have all put back together. No crank. Checked starter relay no trigger no supply. Ignition switch operating as it should. All new good grounds and wires. 1991 4.0 xj fuel pump all works except no power to starter relay. Will turn over if starter is triggered manually small wire from starter is good to relay. Any help. Maybe clutch safety switch?

Re: No power to starter relay?...

A 1991 doesn't have a clutch switch. The manual wiring harness should be providing the ground to the starter relay, whereas the automatic wiring harness routes the ground through the neutral safety switch. I didn't need to do anything with the starter relay when I swapped my 89 from the ax15 to the aw4.


Looking at the starter relay in the PDC, the trigger coil should already be grounded and the triger voltage comes from the ignition switch. Looks like power to the contacts that feed the starter solenoid come from fuse F5 in the PDC.
