|Ford motorhome ignition problem||Rick||5-28-14|
|My 1999 ford motorhome would intermittently not start but acc. Would work and now nothing. Starter and battery are good. Think it might be the ignition assembly switch, any thoughts would be greatly appreciated.|

|So we either have (85% probability ) a bad ignition switch or the components from the key down the steering colum are worn out. The other 15% is an electrical problem you will have to check for.|
The ignition switch is on two studs or bolts below dash level. Depending on trim and base model the switch may have one or two harness plugs. Standard motor products has a picture of the switch in their on line catalog.http://www.standardbrand.com/Online%20Catalogs-eCatalog/Content.aspx
To test, remove switch, inspect harness plugs where the plug in, common failure is a switch that wears out gets hot and damages the harness plugs.
Means a new switch and new repair conectors. You might get lucky with stealing a harnes off a wreck, but I wouldnt lay a bet.
If you don't see a obvious problem, get a test light out and check for power feeds, there are normally two or three, your local auto parts store can probably print you a wiring diagram. Rtail oriented stores usually provide this service either free or cheap.
