Starting problems

The Ford V10 has 2 starter solenoids but both are not shown in their diagrams. We had these exact same symptoms until one time it would not start no matter how many times we tried. At that point, we had already replaced the solenoid up front but had read about one that is accessed either thru the doghouse, or by turning the wheel to get behind the front passenger tire area. Tried the doghouse first - arms were not long enough. Husband finally got to it behind the tire. No more problems. It was intermittent at first, then became - how many tries before it starts this time gradually taking more and more tries. Sounds like the same thing.

Ours is a 2000 Monaco

Thank you.

Lumber, welcome to the forum. There are several solenoids in the circuit to the starter. There should be a master power box under the hood, on the driver's side. Disconnect the starting battery and then check the connections inside the box, by actually removing the bolts and wires, inspecting the wires and crimped on connectors, and reinstalling it the same locations. As for the location of the location of the other solenoids, I am not sure on your make. Try following the "+" cable on the starting battery, to find other ones. If you find no problems, try measuring the single voltage from the key switch when in the start position. Good luck and get back to let us know what you find.
