I have a 1985 Chevy Itasca M/H on a G30 chassis. I have replaced the starter,(original problem), the HEI Coil distributor cap and the ignition switch. Yesterday, after putting it all together I took it out for a spin to make sure that it functioned properly. This morning I turned the key and absolutely nothing happened. I had the battery tested and it passed. I have not searched elsewhere due to being at work. Any suggestions to troubleshoot before I get off work. The Chilton's I have is not very good.

 

Did you check to see if the battery was dead? You said you had it tested, but was that after that morning that it would not start?
Maybe there is a circuit draw from what you installed.....

 

Battery tested good at O'reilly's auto parts store.

 

Is it now doing the same thing it did before you changed the starter? If so then the starter was not the problem. Possibly the ignition switch, starter solenoid, relay, etc.

 

Three new batteries installed. Ignition switch is good and there is power to it. Still have to double check the connections at the starter after work tonight. Also will double check the the cabling between the Battery and the starter. Any other areas the require my attention, please advise me. Still no start.

 

It ran, and now won't, so since you put it back together, something has changed. Did you check all fuses, and relays....?

 

Check the negative battery cable at bot ends, not only at the battery. If it is corroded or a loose connection at the other end it will give you the same problems.
