>Is there a way to test it?
I'm not familiar enough with the SL you have to say of an easy
way. But, if you drop if off here ar my house, I'll seuss it
out fo ryou and by fall we'll now for sure. Aww hell, I'll jsut
fix it for you nice guy that I am.
Failing that...
Common sense says take it off, and apply a voltmeter. With the
schematic you might/should be able to find the wire that signals
intermittant operation and check that out with a voltmeter.
