Re: cat 3512B loading complain

Use ET Status screen and monitor throttle position and fuel position both should increase as load is applied


cat 3512B loading complain


we have Cat 3512B with prefix PTM  after complete overhaul and changing all the injectors by a new set  , 

every time we test the genset by the loadbank it fail to compansate the speed at any load ,even 50 kw make the genset to go down to 1400 rpm 

keeping in mind that we use the pwm as a direct fuel control as per the drawing here


and also we notice that the desired speed is zero during the generator operation 

the injector solenoid test and cutout test was done successfully


any suggestions plz ,,,,,,
