Re: Engine cranks in any gear?
You pulled the relay and you have a wire diagram.. Test, dont guess.
It's not the relay.

Re: Engine cranks in any gear?
Basically, I'm asking if ignoring this issue will strand me, damage something, burn my car down, or do something else nasty. I WILL NOT start it in gear, so no need to worry about that. Even if I did (which I won't), I always use the parking brake, so it's not going anywhere.

Re: Info about installing a JDM PCM in a USDM car
So I have an update.The JDM PCM that came with the harness I bought, part number 37820-PSA-J84, is a direct drop in replacement for the original PCM. It works flawlessly with the stock harness, as well as the JDM harness I bought. The only odd thing is that it sets a P1713 code when the shifter is put in 2, and it has a flashing key light. But it drives fine and there are no other problems. I'm just not sure if it would pass an inspection with this PCM, but we don't have inspections here, so it's not a problem for me, but it may be for you. Thanks for your help guys!

Re: Will an alternator fry if it’s overloaded?
Well I think I killed my alternator running my inverter off of it. I was drawing about 300 watts from it constantly for about 4 hours, and 2 days later, the alternator is dead. The alternator was full fielded producing a steady 13.4 volts the whole time. Could very well be a coincidence that it died right after I ran the inverter off of it, I don't know. I bought a rebuilt 160 amp alternator on Ebay. I have other alternators, but I'm sick of replacing these crappy OEM alternators every couple of years. I've also been stranded, 2 times from alternator failures, and I'm just sick of this.

I have never replaced an alternator in one of my Honda’s. I think the OEM ones are great.
P=IE solve for I. I=P/E
300W/12V = 25 Amps. That’s not straining it much.

Re: Will an alternator fry if it’s overloaded?
From my experience, I disagree that OEM Honda alternators are great. It was replaced twice by the dealer under warranty, and then another 2 or 3 times by me. But you're right that 25 amps isn't that much, so maybe coincidence. As I understand, when an alternator is pushed beyond its current limit, it just won't output enough power and the battery will drain as a result. As I understand, nothing will be damaged. Is that correct?

Re: Will an alternator fry if it’s overloaded?
That is my understanding as well. Alternator supplies 100 Amps. You need 120 so the battery gives you 20 Amps on top of the alternators 100 until the battery dies. I would think it’s also not designed to run at max load all the time and engineers pick output based on load needs. Car needs 60 Amps to run so we will put a 100 amp in to not over do it. Sure running a 100 amp alternator at 100 Amps often will wear it more but you were drawing 25 Amps off of it for 4 hours not 4 months.
I think you have other issues if you are going through OEM alternators like that. Not the typical at all.

Re: Will an alternator fry if it’s overloaded?
you should make sure the alternator cable is thick enough to handle the upgrade. 160 is quite a jump and manufacturers generally don't waste money on thicker wiring than is needed. it may save you from writing a post about melted wiring or fried fusible links.

Re: Will an alternator fry if it’s overloaded?
If an alternator can't be damaged from a heavy load, why do almost all alternators say to fully charge the battery before you start the car? Don't they say that so the alternator doesn't overload and fail?
