Question about 1998 Jeep Grand Cherokee
Hello, Need pin out voltages for a 98 grand cherokee larado connector to the cluster .( RHDrive )
Not willing to insert a new cluster untill loom checks out. My connector shows different to the infrmation provided by a friendly Adelaide jeep dealership. ( South Australia) Most manuals show this info but have only got wrangler and cherokee CD's not Grand cherokee 98 !!!!
Also, most diagrams show 2 ground terminals and mine reads as if there is no earth. I HAVE left and right indicators, one (fused at kisk panel fuse group OK ) constant 12 volts one 12 volt ign.start run, one dimmer control terminal, and 2 terminals reading 2.5 volts approx , assume these are the "bus" lines.
WHAT are the others and does any one know how to check out the new cluster to make sure it is the correct one ????
Have had an intermittent Failure of fuse control coils of auto shut down and fuel pump relays for several years now .fault goes before able to trace it. Longest the fault lasted was 20mins but still unable to find cause by discconecting items etc.As soon as I start looking for short in circuit before or in parallel with the relay coil circuits the fault disappears and I haveonly moved the power distribution box cover and tried to insert a test light in the circuit. Ffinally cluster has failed permently on all but hard wired items .ie no gauges and warning lights but dimmer control and ABS warning light working? . vehicle towed home. Fault gone no fuse blows but still no cluster. All other systems working .
My non genuine wiring diagrams show only imobiliser on same circuit but this system works although I am not sure if the chime worked immediately,. I think imobiliser is in module with sound device etc. But not sure .
Have stripped out loom around power distribution box - no visible damage and no electrical fault between relay coil to power control computer . Any way if there was an earth ing fault there the fuse would not blow. Must be a fault between fuse and relay but this goes into the main loom and difficult to get to. If I bypass it car starts now because there is not a problem. When I tried to bypass the fuse with another in line from hot side of fuse to relay input with the problem, the car started and then I found the problem goneso ofcoursethe car started . returned wires to original but cluster not working! !!!!!!*&^*^&%
