My original engine has failed after 25 years of use. I have decided to repower my SImplicity with a newer Briggs engine. The new engine is a Model: 49T877 Type: 0006G1. What I need help with is what wires from the original harness connect to the new engine harness.
From Tractor harness:
Gray - Same connector with Red/White - Originally connected to serrator
Red/White - Same connector with Gray - Originally connected to serrator
red/yellow - to engine block
Black/white - to coil
On new engine
Black/gray - to coil
gray - to fuel pump
red with red jumper - to voltage regulator
Any idea how to hook everything up? Mowing season is right around the corner.
1- alternator part number 592830 should have 2 wires going into a yellow connector that connect to voltage regulator 845907
2- .wire from voltage regulator to battery needs to be fused
3 - fuel shut of solenoid part number 798779 should have 12 volts when start switch is in on position
4- Coil should have a kill wire that stops engine when connected to ground through safety switches and start switch.do not apply 12 volts to coil wire.
I will take a go at this

1- correct have this connection
2- from voltage regulator (engine harness]: red wire w/jumper fused to where?
3- fuel shut off will have black/white wire connected to gray (12volts when switch is on)
4- coil (black wire on engine harness) will have red/yellow wire as kill wire.
From tractor harness this leaves me with 2 wires that may or may not need connection.
In the same connector with a red wire (12volts when switch is on) and gray wire (0 volts on or off) which do one hooks to the voltage regulator (red wire with jumper)
the red wire from voltage regulator connects to positive on battery may go through the switch some do . it is fused in case of a short circuit in the charging circuit. Could be fused before start switch on B terminal. The case of the voltage regulator in negative or ground.
