well? anybody know? i dont.
For what section? I'll tell you this for fuses- injectors, fuel pump, egr sol is fused at 10A, crank at 3A, and ECM at 10A. If you want actual current draw, I would have to measure.....
Why do you ask?
Add in another 10 amps or so for the fuel pump.
im looking to make it so my TBI system is on its own power switch. the harnes i am getting from a good guy is a stand alone harness.... so im wondering if one of those 30A battery shut off switches will work or not.
You don't want to switch main power to the ECM off. As you drive, the ECM "learns" how to make your engine run as good as possible. It stores the data that it learns in volatile memory, so if you disconnect the power, then it has to start learning all over again when you power it back up. /forums/images/graemlins/frown.gif
What's the reasoning for wanting the TBI to have a switched power source? If it's for anti-theft, just put a switch inline with the ignition lead from the distributor to the ECM. The ECM won't fire the injectors if it doesn't see that signal. /forums/images/graemlins/cool.gif Of you can put a switch in the fuel pump main power feed.
oh, i didnt know it was a learning system. good info to know.
mainly theft protection. but also as a kill switch for if something goes wrong. there are better other ways to do that. and i plan on having 2 or 3 of them since i wont need a key to start it.
The best kill switch is gonna be to cut power to the distributor. /forums/images/graemlins/cool.gif
