I have a 1998 jeep wrangler sport 4.0L.
When I key on the jeep it kills the battery instantly. When I hook up a jumper cable to it it will start. Replaced the battery and still same drains battery instantly. Checked the alternator and it is good. Disconnected all main power cables from battery to single out which one was cause issues. This led me to the engine compartment fuse box. This then led to fuse #17 causing the issue. Started unplugging all components attached to that fuse to find the power draw was coming from the cluster. Removed cluster and took it for service after testing the cluster shows to be working as it should. So far I’ve trailed the issue to the cluster but at this point I’m stuck again. I’m trying to find out what the cluster closes the circuit to that could be causing such a crazy power draw only at the point of key on.
