[Al Evitts <albert@domain.elided>]

Help:  Bought a new 75 Scout over the weekend.  While flushing out the
road tar the PO had for oil I was leaving the engine run.  About 10
minutes later the engine just shut off as tho the key was turned off.  I
now have;  no lights no accessories no gauge movement,no start, no power
at coil with switch on.  I have power at the battery connection on the
starter.and no further.  No blown fuses.  Any body got any ideas as to
what the check?   TIA
