Diesel engine for the generator will not start so I'm debugging the problem. Have the above diesel gen unit and measure only 7.5 volts to the fuel pump which seems to be low. Manual states fuel system operates at 12 volts but design could be such that a lower voltage is applied to the fuel pump. I called Onan yesterday but have not had a callback on my problem.
Looked at the installation manual but I cannot find the fuel pump in the schematics so I cannot trace from the coach cable into the generator control box to the fuel pump
. Does not make sense...voltage should be 12 or 0!!!
Any ideas how to solve this problem other than taking to shop? Thanks for any help.
