Electric starter relay
The electric starter on the MTD engine uses a relay
that acts as a remote switch instead of a solenoid, which
would also move the bendix gear out to engage the fly-
wheel. The bendix gear on this starter will move to engage
the flywheel by centrifugal force. The relay is mounted on
the side of the engine, next to the oil dip stick. See Figure
6.13.
To remove/replace the starter relay:
1. Unplug the starter harness. See Figure 6.13.
2. Remove the screw that secures the relay and dip
stick tube using a 10mm wrench.
3. Disconnect the two 12 AWG wires from the bottom of
the relay.
4. Disconnect the relay’s ground lead from the middle
tab of the blade brake switch. See Figure 6.14.
5. Work the lead out of the two retaining clips.
6. Install the relay by following the previous steps in
reverse order.
7. Test run the engine before returning it to service.
