Wiring

CONDITION. All wiring must be fully insulated between connection points, securely fastened and free of

foreign material (such as rust and corrosion) at the connection points. This is especially important in the

use of batteries where much of the potential may be lost due to loose connections or corrosion. Remember

to check the insulation on the wire. All it takes is a pin hole for a wire to "ground out" on the engine or frame.

This is of special concern when moisture or water is present. This may cause the engine to run erratically

or be impossible to start.

WIRE GAUGE: Proper thickness of wire is necessary in all electrical circuits. Wire diameter is measured

in increments of gauge numbers. The larger the number, the smaller the diameter of the wire. The smaller

the number, the larger the diameter of the wire.

1. Starter circuit wiring must be rated at #6 or lower gauge number.

2. Charging circuit wiring must be rated at #16 or lower gauge number. (20 amp system requires #14

or lower gauge number).

3. Magneto circuit wiring (ground circuit) must be rated at #18 or lower gauge number.

Color Codes

Tecumseh Products Company standard wiring color codes effective August, 1992 are as follows:

Code Product

Yellow - Alternator A.C. Leads

Red - Alternator D.C. + Leads

Brown - Alternator D.C. - Leads

Black - Alternator Ground Leads, Battery Ground Leads

Orange - 12 Volt Starter B + Leads

Dark Green - Ignition Shut-Off Leads

NOTE: Prior to August 1992, wire codes changed according to model and specification numbers.

Ammeters

An ammeter is used to measure the rate of current flow from the alternating system to the battery. If no

current flow is indicated by the ammeter, remove the ammeter from the circuit and check all other

components in the system. Use the ohmmeter to check continuity across the ammeter. If no continuity

exists, replace the ammeter.
