If you are replacing your ride on mower engine with one of the new Briggs & Stratton Single Cylinder Ride on Mower Series Models, the wiring loom and connector might be slightly different to your old model, depending on what brand of ride on mower you have.
Your mower will have a starter motor engaging solenoid, so you must connect the wire that runs from this solenoid to the terminal on the starter motor. The terminal is located towards the base of the starter motor.
We have listed below, the wires found on the new Briggs & Stratton single cylinder engines and where they need to be connected to.
RED WIRE - This is your DC cable, it should be connected directly to positive power on your battery. This wire charges your battery.
BLACK WIRE - This is the engine kill switch, It needs to run to an ON/OFF switch and then run to earth. DO NOT CONNECT THIS WIRE TO POSITIVE POWER!
GREY WIRE - This needs to run to an on/off switch and then to positive power on your battery, this controls the carby solenoid for fuel.
ORANGE WIRE (IF FITTED) - Can be connected to headlights or any other accessories

Replaced old engine 33R8770033G1 with a new EX1900 33S8770019G1. Six pin connectors and 2 pin connectors fit right but headlights will not turn off when mower is shut down. what is causing this? Is there a simple fix so headlights lights work like they are originally meant to do so? This was the engine recommended for an exact replacement. Please advise. Thank you.
