BRIGGS & STRATTON ENGINE REPLACING ENGINE OF ANOTHER

MANUFACTURER

When replacing the engine of another manufacturer with a Briggs & Stratton engine, the equipment

requirements must be known so that the replacement alternator system has the same output as the original

system provided.

Often the equipment wiring harness is not compatible with the Briggs & Stratton alternator output harness. To

create a compatible system it may be necessary to modify the equipment wiring harness. To do this, a wiring

diagram for the equipment is essential.

The original keyswitch may also create a problem. Even though the keyswitch harness connectors

appear to be identical, there are internal differences to keyswitches. Therefore it is necessary to have

a diagram of the keyswitch showing the terminal positions and their functions. For example, see the

5 terminal switch diagrams in Figure 1 and Figure 2. The keyswitch in Figure 1 is compatible with all Briggs &

Stratton alternators. Note in Figure 2, that when the “brand X” keyswitch is in the START position there is no

battery voltage available to the #2 switch terminal. Consequently, if the replacement Briggs & Stratton engine

was equipped with a carburetor solenoid, it would not function. This is why it is important to have a diagram

of the keyswitch when replacing engines, or replace the keyswitch with one that is compatible with all Briggs

& Stratton alternator systems.

It is not possible to show all of the wiring diagrams or keyswitch combinations that are used by equipment

manufacturers. However, the following wiring diagrams for the most popular Briggs & Stratton engines may

be used as a guide when replacing an engine. The wiring diagrams show the type of keyswitch that is

compatible with the alternator system shown.

NOTE: The 5 terminal Briggs & Stratton keyswitch, part number 490066, shown in Fig. 1 has been replaced

by a 6 terminal keyswitch, part number 692318. The additional terminal provides a direct connection

for the charging lead at the keyswitch.
