HOW TO TEST MODULE(V-4)
Then with new module, contact red meter wire to red Ignitor wire and black meter wire to base plate, it should read about 1.15 or 1150
*If system has blown, will read (0.520 / 520 ), normally power transistor
has blown due to coil overload .
* If power transistor has been damaged, will read .800 to .900
· If shows a ( 1 ) on meter, there is a break in wire, a terminal is loose,
or has internal break inside module
· If module smells of smoke/burnt, this would show that has been destroyed by connection wires incorrectly(wrong polarity), or that have fitted electronic or faulty coil with internal shorts. No warrantee normally on these items.
Then with new module, contact BLACK meter wire to BLACK Ignitor wire and RED meter wire to BASE plate, it should read about 0.680 to 0.720.
A failed unit will read about 0.520 or 1(open circuit)
Then with new module, contact red meter wire to red Ignitor wire and black meter wire to black Ignitor wire, it should read about 1.15 to 1.25.
A failed unit will read 0.520 to 0.540 , or 1.400 to 1.450
*With system in vehicle, connect voltmeter to coil positive. Turn starter, voltage should vary between 0 and
9 volts. If stays on 0.5 volt, then system has failed.
· Crank starter and see that voltage on coil positive remains between 8 to 12 volts. System shuts down at
· 6 Volts.
* Check for unbroken earth wire inside distributor.
