I have a two ton floor jack I'm hoping can lift up the front enough to access the starter.
I seem to remember checking the Yellow Top was at 13.35 volts, after it had been sitting unused.
I then had the Yellow Top on a charger overnight. With the Truecharge2 connected to the Yellow Top Group 34 I can here only a single click when ign turned to start.
The yellow top had been working ok holding a charge and cranking the Jeep's 4.0L engine.
It does have a date code of 04/08 which makes it approx. 11 year old battery.
I'm just moving the motor home down the road a short ways and don't really want to purchase a new Group 65 battery if it's going to be sitting in one spot and not being driven at all.
Another option would be to pay a tow company to tow it ~five miles down the road.
Once it's moved I may need to move it on the property once or twice. I can then work on it later to get it to start.
I have all the factory schematics, FSM, etc. for an E-350. I'll probably need to take a closer look at the wiring in case the problem isn't the battery.
The check engine light comes on when the ign key is turned. I do have a Snap-On MT-2500 which works with most OBD1 vehicles providing live readout and some diagnostics. However Ford OBD was behind other manufactures in the 80s and early 90s may not have much information when connected to an OBD1 scanner. (other than perhaps a Ford scanner)
