TOOLS NEEDED
Quantity Part Number Tool
1 237-5130 Digital Multimeter Resistor (R5) is used on generators that have three diode rectifier blocks.The "Resistor Test" consists of the following steps:
Disconnect one lead of resistor (R5) from the positive terminal of varistor (CR7).
Connect one test lead of the multimeter to each lead of the resistor.
Resistor (R5) should measure 27000 ohms ( 2700 ohms).
