Starting Problem

I have a 99 Coachmen Mirada, 34' with a Ford V10. I turn on the ignition switch and nothing. No dash lights, the headlights will not even come on. I press the "boost" button and the dash lights cone on, headlights come on, engine will start right up. Both batteries are new and have full charge. Something is preventing the engine battery from sending power to the ignition. I figure it's a fuse or relay but I don't know where to start. Any help would be greatly appreciated.

sounds like battery connections, dirty or bad battery ground

Some Mirada's had a battery disconnect solenoid for the coach and chassis batteries (mine doesn't). If you have a disconnect solenoid, check it to make sure its switching correctly.

Other than that, sounds like you have a bad chassis battery or bad chassis battery connection.

It won't do MACH 2, but I can get a sandwich and take a pee.

I gotta believe it is the chasis battery disconnect switch or selonoid. Here is another thread from here that has info.

Starting Problem

Thanks for the advise and the link. That sounds like it might be the solonoid. The mh belongs to my father, I've just been trying to help him get it going. He has thought for some time that there was a problem with the switch that controls those soloniods. I'm gonna move the wires to the same side as suggested in the other post and see if that makes a difference.

Thanks again,

Instead of guessing about the fix to the problem, it may be time to take it to a real repair shop and get it fixed right.

Prospector, real men (and women), like to roll up their sleeve's and work on their own stuff. That is the only way to learn about what you have and how it works. With the help of knowledgeable online friends, many costly repairs turn out to be simple and easy fixes.

You show up at the repair shop with no knowledge of what you have or what the problem is, the next thing you know you have been talked into changing the blinker fluid.

My father, the.owner of the coachmen, is a retired auto mechanic. He still likes to work on his own when he can, but at 81, needs my help. Not to mention that our regulag TV mechanic was so backed up that is.was going to be September before he could get to it. Surly we can get it going by then!
