[Shop-talk] Since it's been quiet here, I'll add a second questions

[eric at megageek.com]

OK, on my plow tractor (a Hustler 275zero turn) I have flood lights to be 
able to plow at night.

Here is the problem, if I run the lights, they work fine at first, then 
they seem to 'short out' the ignition after running a while.  Problem is, 
I can't find the short.

Is this most likely just a shorted out wire, or is it possible that the 
alternator could be causing a problem?  What are some troubleshooting 
steps I can take?

(Darn, I really wanted to fix this in the summer, but now I've already had 
to plow 3 times here in NJ!)

Thanks
