Figured someone here could help with a problem im having. Old yanmar engine blew up, got a replacement, put in and wired. Ran for about 15 mins then shutoff with the battery light, and 2 lights underneath im assuming coolant and oil lights staying on. When i try to start it, the second light (i think oil) goes out but the other 2 stay on. Has all new sensors. Any ideas? The only other thing i can think of is its parked on a slight incline and maybe the coolant isnt touching the sensor probes?
Check wiring to sensor in top of radiator, had this problem on a TB180, broken wire in the plug...
also check fuel shut off.... Mine would shut off fuel indiscriminately. New fuel shutoff (electronic valve) and its good as new
