Scag Turf Tiger dies right after startup

Earlier, my turf tiger would die only when I engaged the PTO which I worked around by popping the PTO switch a few times til the blades started rotating. Then it would die intermittently die during mowing. Now, I try to start my turf tiger and just as soon as it starts and I release the key it dies.

2001 Scag STT61A--25CH
Kohler 25hp

Replaced:
- Ignition switch
- Relay
- Control module
- Carb
- Fuel filter
- Elec clutch

Checked continuity on all safety switches (brake, steering arms and seat) and rung good.

I am stumped, please help.

What's your battedry voltage? If you have a jumper pack or a known good battery try hooking it up. Are the 2 fuses good?

I left out PTO switch was replaced.

Battery is fully charged (12.4v) and cranks fine.

Did pop the two fuses a few times and the control module connector burnt through and shorted to ground (replaced), still no joy.

The fuse holders are the weak links on Scags...
Replace them with inline fuse holders from Napa or any autoparts store..
Also...inspect your wiring for any melted connectors and replace the terminals..

Maybe the charging system is way overcharging... unplug the regulator

Update: Replaced fuseholders with new ones as suggested. Now fuseholder with yellow wires blows as soon as ignition switch is turned on and ammeter pegs +. Is it possible that the regulator is bad?

Unplug it...see if it still blows...
Somethin is shorted to ground..
Usually the stator shorts out before the regulator does..

I have had that happen. Disconnect regulator as slapper said. Most likely it still will blow. If it does blow look at wiring behind the control panel that has worn and shorted to the metal. This year I had it short there. It was my 3rd wire repair over the 5khrs the mower has so I decided to just get a new harness ($200) to resolve the covering on the rest of the wires thinning.

Key switch is shutting off the fuel solenoid on the carb.
