Hi Troops,
Replaced the engine on my TC 2 weeks ago but the previous cranking problem is still bugging me!!! So today I took a color coded copy of the electrical system and with the use of three digital multimeters and assorted jumper wires, I diagnosed the cranking problem to be the Interlock Module. I went on line and did a search with "scag 483029", which is the part number of the Interlock Module and I found that this module has been problematic and superseded to Scag P/N 483599. Evidentally there has been a problem with the 483029 module and it showed up when it receives all the correct cranking circuit inputs and then supposed to send voltage to the starter solenoid which in turn sends high amperage to the starter motor. This module is found on the vast majority of Scag mowers both zero turn riders and walk behind units.
So, if any of you have a machine with a cranking problem, check the part number on the grey plastic module and if it is 481808 or 483029 and you have an engine cranking problem, this module may be the problem.
The replacement module for 483029 is 483599 and is pricey, but I'm need to buy one as my machine is out of warranty with the exception of the new engine and the intermittent cranking problem is starting to "blow up my Kilt" so to speak!!!:smiley_aafz:
