|1999 Fleetwood Discovery Motor coach||Mitchell Burch||4-20-16|
|I cannot get my coach started. Batteries are fully charged, but it will not crank. Is it starter, what is it. I am totally frustrated!|

|This is a pretty basic trouble shoot.|
You know there is a start battery and house batteries that only charge together when the engine is running?
Use a test light with a REAL BULB for these tests and hook it to direct to the negative battery post.
Check in order Power to big terminal on starter while cranking (or trying). Light dim or goes out means dead battery, or poor conection on positive side.
Check power to little terminal on starter while cranking. No light means bad relay, conection fuse, breaker, neutral safety fault or ignition switch.
Check ground between chassis and engine while cranking and also engine and negative battery post. You still leave you wire hooked to the negative post, if the light comes on, it will likely be dim, this means a ground path fault.
If you test good for all of above replace starter.
