After talking to a local alternator
repair and rewinding shop, the specialist said they have modified of the kohler gensets. The ADC 2100 board is a computer with AVR which is needed to regulate the alternator
to produce 120v/240v.
Coincidently, my friend who is using 13EZOFD has a problem with his genset giving error code of CC1 and SCF0. SCF0 = software
communication fault 0 is the computer board gone bad and had to be replaced?
So this what the common modifications are made to the gensets:-
1. Remove the faulty ADC 2100.
2. Install a separate universal AVR to the alternator end. All this is done by the alternator specialist.
3. The mechanic
will handle the basic engine
side, rewiring the sensors ie low oil
pressure, low coolant
, high engine
temperature and no raw water
flow, etc to control relays to cut off the power to solenoid. The engine speed is controlled by a mechanical governor.
Interestingly the engine block of NL for 0.762 liter comes from Japan
manufacturer which supplies to Perkins
Will keep my progress posted here on the modification.
