control box or unit question.

Anyone ever test there control unit input voltage too #11 mine is 10.56volts with ignition on anyone get battery voltage as the book says?

[Oldblueaccord]

Whats your input battery voltage ? should be about 12.7 or so at the terminals?


Give me a littel more info into what #11 is and I can try testing it for you. Usually I get 11.5 volts on most things with the car OFF.

I think a carparts place can check coil outout for you if you take it to them. If the car is running there are plenty of diagnostic places that can scope it for you. Remember its up wards of 25,000 volts so some meters can get damaged.

Thanks for responding #11 is actually the tach signal it goes from the coil Neg it's a blue wire, too the fuel pump relay and also the control unit terninal #11.

carefull probling around the ecu if that is what you are doing, they use their own DC reference voltage and not the car's 12VDC

I'm testing per Honda testing proceedure book specs.
