Starter on 89WB

[dctrcarter]

Hi, all Richard here from Decatur Il. Was on a small trip after new
tire, new oil, things checked out underneath, got to Missouir an turned
coach off, wouldn't start again. The ignition switch would turn on
Acc. but as I turn it to the start, nothing. This happen to me before
an turning the key back an froth a few times an the ignition would
catch an start, not this time, haad to jump across the starter on the
engine, it started right up.Took the ignition out the keys works loose
in it, so thinking it this ignition switch, can't find one it is --
Pollak-31-158-100, can't tell you if its the original switch, I would
say no. Any ideas?
