Hello:
'96 Discovery 4.0L, auto box, NAS
Battery installed and uprated to a yellow top Optima in spring of 2006. Starter installed and uprated to a Mean Green fall of 2006.
The following has been a gremlin since before the various installations. I turn the key to the on position and wait for the relays to stop clicking then I attempt to start the rover to my chagrin the starter spins and the bendix gear does not fire. This is very dodgy to say the least. So, I replaced the battery it was time anyhow. Gremlin went away for a few weeks. Then it started again. I replaced the starter (over 110,000 mi. through and through). It worked wonderfully for a few weeks and now cropped up again big time.
I have attempted to start the vehicle by jumping the terminals on starter [using the appropriate tool of course] thinking that a relay may have been stuck somewhere. No luck. Are there any relay that need testing? I have jumped the car with mixed results.
I'm thinking poor/corroded wiring and am considering replacing the positive and negative cables to the body, starter and the under hood fuse box. What are your thoughts?
