Small Engines (Lawn Mowers, etc.): Diode Harness, snapper mower, rider mowers

Question
I have a 1986 Snapper mower with a B&S engine and a magnetron ignition.  I purchased a new diode harness with two diodes.  One end hooks to the hot side of the solonoid. The other end goes to the ignition.  I can get power from the solonoid to the diode, but not past the diode.  This harness also has an end that fastens to the light switch with a diode.  Might you know why I cannot get power past the first diode?  Also, can I bypass these two diodes?

Thanking you for your reply!!

Hey Orland,
I dont have much experience with these rider mowers but what you have to do is check for interference. Look for matal to metal <a href="http://www.ntsearch.com/search.php?q=contact&v=56">contact</a> on the diode or soleniod. If there is no interference the ignition is probably gone or you <a href="http://www.ntsearch.com/search.php?q=battery&v=56">battery</a> needs changing. Hope this helps. Let me know how this works out.
