91 Isuzu Trooper won't turn over Sign In

Hi, hope someone can help on this one...

1991 Isuzu Trooper V6
Manual Transmission

Returning to my vehicle in the parking lot a few days ago, I found I could not start it, it was completely dead. For some time before, I had been having trouble with the starter not immediately engaging the flywheel -- just sitting and spinning for several attempts before turning over. This being the case, I assumed the starter must be at fault for the not starting problem, and after getting my vehicle home I installed a new starter. This didn't help, though was probably needed anyway.

The new problem is strange. I have replaced both the battery and the whole starter, and have checked that the starter relay engages and closes. The problem is this: with the key out of the ignition, I can turn on the headlights, as usual. When I insert the key, and turn to "on", the dash lights come on, as does the radio. When I turn one more position to "start," I can hear a click (presumably the starter solenoid), and then nothing happens. The radio is dead, the dash lights are dead, the headlights won't come on, no buzzers, nothing. Turning the key back and forth, removing and replacing, trying again, doesn't help. If I go away and come back later, however, I might be able to get the normal signs of life again (as if magically fixed) but when I try to start the engine again, the whole thing dies again.

Any ideas on what is going on, and how I should proceed?

It sounds like you have a corroded connection somewhere. Clean the battery terminals & cable real well..... While the battery is disconnected trace both cable to where they connect on the engine. Take those apart & clean thoroughly as well....
