Another dumb Original Cub Cadet question
 

after reading Roland's diagram for the wiring harness...im kind of stumped on something stupid. on his Voltage Regulator, it has 4 lugs that say F, B, G and L. on all my voltage regulators, i have either 3 lugs that say F, Bat, Gen. or the voltage regulators with 4 lugs that say F, Bat, Gen, Gnd. what is L on the diagram? im trying to figure out why my Original only has spark when the push button starter is pushed in. any help would be appreciated.

The "L" terminal is for "Load". It is for machines with extra electrical accessories such as lights.

If it only has spark when the starter button is on, you have your ign circuit goofed up. It doesn't have anything to do with the regulator.

im confused because on Roland's chart it shows that the green wire from the on off key switch goes directly to the L lug on the voltage reg....but i don't have that L lug, so where would i attach it? Batt, Gen, F, Gnd? also, it loses spark when the voltage regulator is bolted to the tower...and regains spark when unbolted and dangling. im stumped.

Check the wires on your start button.

One terminal should have a battery cable AND a small wire that goes to the "Bat" terminal on the V/R. The other terminal (on the start button) should ONLY have a wire that goes to the "A" terminal on the S/G.

If the small wire on the start button is on the wrong terminal, this would cause exactly what you describe.

Check all your grounds first then see what is really going on ! A loose ground / poor ground will drive you crazy with other issues , " back feed grounding " spark, no spark high/low or erratic voltages . Also don't forget any bonding such as motor to frame!:bigthink:

Woops, didn't see your last post...

You have the wrong (or a different) V/R.

Hook the green wire to the "bat" terminal and bolt the V/R back to the tower.

This should work, providing that everything else is wired as it needs to be for that regulator.
