OK so, First: Problem, i just finished changing my clutch and started my car last night to take it on the first break-in drive. the battery is pretty old and it needed a jump when iput it back in. I took it maybe 5 miles around the neighborhood, i hit a corner a little fast and slipped the tires SLIGHTLY and the tach died. So i take it home, turn it off, turn it on, it works!.....10 seconds later......dead again.

Ive narrowed it down to either

Slow cranking causing the ecu to shut down the trailing coils (read it on this forum)

Bad trailing coils

Bad ground, somwhere? (ive checked all my wires and grounds)

Cold solder joints in the instrument cluster

thats all i have been able to find. I will test all of these today, just wondering if i missed something

Thanks in advance

 

Checked battery = 12.25v <- LOW

Checked Trailing coil when tach dies and CEL pops up = Coils went from 2.3-3.6AC or so to .1 or nothing

My guess is new battery, the battery i have is OLD and is low on voltage, so, we'll see i guess, could use a new battery anyways, just, im so ******* broke already from the clutch it isnt funny, lol

 

Anything else i should check?

 

i bought a new optima red top battery today and will be installing a nice 24k gold plated positive terminal, and probably another one for the ground.

Seems as though the battery didnt do much, it cranked almost healthy a few times today, none of which were when i first put the battery in or have any consistancy

The tach stays on most of the time at idle, but as soon as i add a load it dies within a few minutes all the way down to a few seconds, no consistancy with when it dies

given the symtoms im going to rule out cold solder joint in the cluster

gonna check grounds the next chance i get and im gonna also check the starters connections and ground

Any other suggestions are welcome

 

well forget it, just close this thread please, its kinda useless

 

I feel like an idiot, i guess when i installed the tranny i knocked one of the ground off for the chassis on the firewall right next to the wiper motor, slapped it back on and everything works even better than before, i think the new battery helped alot

 

You need to re-title the second pic in your sig as "Lo Pan's RX-7"

Off-topic, sorry.

 

ummm....no.....that is my RX7 at the top of the IKEA parking lot at a little photo shoot in emeryville in august

 

Yeah I know ... I was there. =P

But that pic totally looks like Lo Pan, you know, Big Trouble in Little China?



The light comes out of his eyes as well.
