Police 3: Battery cable to the starter along with ancillary wires to voltage regulator and ignition switch

Created: 2012 February 20

Updated: 2015 August 18

Applicable to these part numbers:

• MG# 13749441

1. The thick battery cable gets routed down to the left side of the transmission near the starter. I always route this wire between the battery tray and the rear fender in the little triangle space that is available there. I route the wire straight down behind the swing arm member, and then route it forward toward the starter area.
2. The thick battery cable crimped with the two red wires is connected to the positive terminal on the battery. Note: The battery ground cable should NOT be connected to the battery at this time.
3. Connect the heavy gauge black battery cable to the 8 mm post terminal at the rear of the starter solenoid. Secure the battery cable to the longer of the two 8 mm posts, located furthest from the body of the starter. As a sanity check, this should be the terminal that does NOT have a very short connection wire directly into the body of the starter.
4. The red wire with the 4 mm male bullet terminal is plugged into terminal 30/30 on the ignition switch.
5. The other red wire is connected to the voltage regulator
