    Low battery voltage

    Will low voltage kill your injection system?

    I was running down the lake the other day WOT(still only 5400 rpms) and the motor just cut back to 2000 rpms and then back in a matter of a second or two, kept going and it did it again.

    I was told my battery was so low that my fuel injection probably cut out. Put a new battery in and two hours later my guage was reading just over 12 volts again, at idle. Cruised home at 4000 RPMS and noticed it started to sputter again, down to about 3200 rpms and then back up to 4000


    Any ideas


    Thanks

    sounds like a fuel supply issue, may want to check low pressure pumps.

    My tach shows 14 volts when running. Doesn't sound like a battery problem though.

    You should definately check the fuel system. Running lean at high RPMs is the last thing you want to do with and hpdi.

    ensure the ground wire on the back of the engine is tight to the block and no corrosion and if it is, check your filters.

    Just put a tester on while the motor was running. I am not getting a charge from the motor.


    Not a fuel issue, but a voltage issue
