You sound like you're on the money. Should work fine, no relay needed...

i believe removing the original white/red b+ wire from the alternator is going to disable the stock voltmeter how can i hook it up so it works, sa rx7?

silly question but falcon alternator puts out 108a and i think the aftermarket replacement ones are higher. is the 100a fuse ok, wouldn't the alternator maxing out blow the fuse?



yep it will.. but most setups wont reach that.. i have had a couple of high horsepower cars start to melt the 100 amp fuse cause it was close to it blow threshold so there is a 120 amp fuseable link you can get..

twin 8 gauge cable is rated at 200 amp, so stepping up fuse wont hurt it.

I had a question and this is obviously the right place to ask. I started my car up for the first time today and noticed the battery voltage was quite high (15.6V). I double checked it with a multimeter and the reading was accurate. I read trough the first page and figured out my issue (thank you), i had a question about the fix however. I am currently not running anything to the L terminal and i am thinking that's what's causing my issue. My question is, can i eliminate the relay from your diagram and just run a wire from the L terminal to the battery with a diode inline? I don't have a charge light and don't really care to add one. I'm sorry if the question has been answered but my eyes got tired after page 7. Thanks in advance.


Allen


as i have said time and time again.. all the talk in this thread is "oh it didnt work but i didnt connect so and so"

wire it how the diagram shows.. connect ALL terminals.. and how i have stated.. it will work perfectly and be reliable providing the alt is upto scratch



you connect the S terminal to where the B+ terminal is sourced from.. so if alt B+ is connected at the starter cause the battery is in the boot. then S terminal goes to starter terminal..

or it will go into limp mode and punch the 15+ volts..

the point of the L terminal is for trigger to start charging and to show if it isnt charging..



connect all terminals how the diagrams state..

Just doing an upgrade to EL Alt in a S2 RX7 and just want to check something

Can I run the wire for the charge light(relay pin 30) to the white/black wire of the original Alt plug and run it thru the choke/check relay and also can I run the IGN(relay pin 85) to the black/white of the original Alt plug or do they have to be hooked up direct to the charge light and 12v IGN.

Have everything else hooked up as per the EL diagram but just not sure on them two wires.

Don't want to hook it all up and let all the magic smoke out of something or stuff the Alt

as i stated in pm. toss the choke check. not needed anymore..

use the ignition supply for that relay (choke/check). black/white wire at choke/check relay plug to terminal 85.
take the yellow/blue from the choke check relay plug, as thats the charge light im talking about to terminal 30.
use the black wire at chock/check relay plug to terminal 87.
then terminal 86 goes to the alt

Thanks Simon

I have it hooked up as follows -->charge light(relay pin 30) to the white/black wire of the original Alt plug and 12V IGN(relay pin 85) to the black/white of the original Alt plug, relay pin 87 to earth and relay pin 86 to ALT

Have had it running and getting between 13.5-14.1V back to the battery

Will having it hooked up like this cause issues? If it will then i will delete the choke/check relay.


Where roughly is the choke check relay located?


Cheers for your help

hi mate,

well it's not charging correctly so yeah it's got an issue...

choke check relay has a 4 pin and a 2 pin plug to it..

Jaycar do 5 amp rectifier diodes. Just use two in parallel.
