Kohler 150REOZJF 150 kW Diesel Genset - Page 3 - Answered Questions & Fixed issues

the parts manual is a tp-5317 which I do not have . You said its a dec2? or a fast response 2? What is the part number off the main circuit board in the control box?

if you have an scr pack, that has 6 pins, there are two for ac, two for gates, and two for the excitation field. The two gate wires come off your adc controller.

http://www.kohlerpower.com/onlinecatalog/pdf/g2058.pdf Safety shutdowns:

1. Loss of coolant
2. High water temperature
3. Low oil pressure

Likely one of these. If no indicators at a panel check at the connector.

There might be two reasons for the failure of generator auto start. 1. It is the ATS automatic conversion control device that does not issue the start generator command after the mains power failure or phase loss operation, or the self-starting relay failure, which causes the generator to not start itself. This situation is relatively rare. 2. It is the generator start battery failure, and this kind of situation is relatively more.

drain the fuel and replace with ethanol free gas

The Kohler 7.5 R had a possible three different voltage regulators that could be used. You need to check there first. Also if you can get it the service manual for these are tp-5110 Which will show you how to test the regulator o the bench. There was a 5 6 and 7 pin regulator that could have been used.

usually means you have to replace the carb and get the gasket with it. when the needle valve develops a problem they don't intend for you to fix it. this has been my experience.

Check your owner's manual

If your mower runs fine, but dies when the blades are engaged, that has nothing at all to do with the starter - or with the engine. There is a malfunction is in either the electrical system, PTO clutch or one of the safety features somewhere. Check all of the belts first for wear or breakage, then if they're OK, you probably need a small engine mechanic, but it doesn't sound really serious.

the remote has separate starting system check the unit it could be the magnetic switch. manual start bypasses this
