Multiple Electrical Issues on 3000 Series

[GTSRider]

This thing is haunted I think !
Last season got 100 hr's of 100% trouble free mowing on this
now 515 hr. Cub Cadet.
This year problem after problem ,and I am stumped.
Here's where I am at now.
1. When tractor goes up and then down a small dip in lawn...it's almost as the
tractor has vertigo, and electrically dies out for a second, then bounces back.
Do these older ( 2003 ) 3000 Series have a vertical sensor in them ?
2. Engine will NOT start ( no starter spin ) ....have to start with a remote starter switch.
Have replaced with factory new parts... new ignition switch , and new
PTO switch. Have new brake switch on order.
What other switch could prevent engine from starting... seat switch seem to work.
One more thing.... engine will die when under a quick load...such as PTO engaged.... and even stepping on forward pedal to quickly.
Do I have bad coils , or does this engine have a part of electrical
govenor in it ?..
Something is affecting electrics when under load.
Any thoughts appreciated.

Unplug the seat switch and see if it will run then. Our 3200 does, the hiccup in the dip sounds like a funky seat switch (or a light driver)

Thanks for the response.... I have not actually gone under seat, but
you get there by removing torx screws.... I replaced entire fuel hose when I got tractor last year ...so I was under seat and above rear end...but can't remember how I got there.

Checked switch under seat... cleaned well under there ...man the crap that ends up there is unbelievable !
Dis connected seat , and gas low warning switch...cleaned...all looks ok.
When I got it back together, I started...through remote starter switch, and checked seat switch by turning on blades and lifting seat...engine died immediately....so I would say switch is ok.
Next I put a voltage meter to starter solenoid and turned new key and switch to start....ZERO voltage to solenoid.
Last thing I can think of here is faulty brake switch ...which I ordered
today..... any thoughts on all of this ?

My GT3200 will not start unless the brake pedal is down, so that is probbaly the culprit. Have you tried jumping across it?

Problem finally solved..... bad connector in short harness from PTO switch.
Stroke of luck that I found it.
Had harness in my hand when I noticed entire ignition lost power.
This shows that PTO switch and harness can prevent engine from running.
Too many circuits tied into ignition on these tractors due to safety Police.

Makes sense. Wouldn't want to start the engine with the PTO on, what could get exciting in a hurry.
