hey everyone, i've been having some trouble with my swap because 1.) can't get my car started, 2.) when i push start my car, the alternator seems like it's not working (reading only 12.8 V+ instead of 13-15 V+) :sad:

i've replaced the starter, and altenator, and recharged the battery already and still the same problem. i'm hoping that if i can get the charging system to run correctly, the battery will get the extra needed boost to start my car. h:

here's my question:

how much influence does the ECU or ELD (electronic load detector) have on the starter and/or charging system? when the car starts, does the ECU send out a signal to regulate the voltage or does the ELD do that? i'm thinking that everytime i start my car, the ECU is either receiving or sending out a false signal to the altenator causing it to not generate the expected output voltage. any insights will be appreciated. :bigok: :thumbup:

 

Have you checked every wire, solenoid, fuse, etc...that has to do with the charging system. Start from the bottom and work your way up, don't just start buying new parts that might not be the problem...

 

yep, already checked except for the ELD

 

Just a thought, but would pulley size make any difference?

 

damn hondas are really picky about grounds. Sounds weird, but throw an extra ground wire on the engine to the frame, and I bet it'll take care of the problem. It has every time I've had the same problem.

 

not really because you can adjust the tension yourself. good idea tho' :thumbup:



hmm, sounds like a plan..good looking out.. :goodjob:

 

I meant more along the lines of if the pulleys are the wrong size, the alternator won't spin as fast as it's supposed to, thus put out less voltage. It's fine at higher engine speeds because of the built in regulator, but at idle, or lower engine speeds, your alt might not put out enough.

Sorry for the confusion.
