distributer problem maby?

mystery · 01-22-2014, 04:14 PM

alright so i fixed the carb base plate and then discovered i had 4 fouled spark plugs so i replaced them. car cranked right up and idled but idle was high let the car run for 5 to 10 minutes then had someone come over that was going to help with my adjustments on the carb. tried to crank it back up and discovered i had no spark comeing off my coils so im not sure if it could be wiring or my distributer... havent been able to get it cranked again but ive probally fouled the plugs again. i had replaced the coils with sum off a older truck and im recently working on swapping those out with factory coils. theres a brand new cap and rotor so those are only things i can think of. any experience on these?

not trailing OR leading? is there power to the ignitors? are the coils hooked up right? did you remember to put the rotor back in with the cap (i forgot once). Is the timing right?

mystery · 01-22-2014, 07:44 PM

guy before me replaced the cap and rotor. and timing sounded good when i had the car cranked for that 10 minutes. he did have direct power running to the coils and i changed that. but i dont understand why it would crank, run, and idle but i turned it off and let it sit for a few minutes then no spark on leading or trailing coil.

check your fuses and fusible links?

See if the coils are getting power and if they are grounded .

mystery · 01-22-2014, 08:41 PM

fuses where good. had to replace those fusible link once but that caused no power at all? is there one other than whats on the driverside strut tower? they are getting power ill have to check on the grounding cause i dont remember changing that and last i remember looking they where grounded to each other?

Whizbang · 01-22-2014, 08:43 PM

so you have 12v at the coils confirmed? You also have voltage at the ignitors confirmed?

have you tried another dizzy?

multimeter all the things!

chibikougan · 01-22-2014, 08:47 PM

The thing is going to be flooded as all hell too. Deflood before trying again.

t_g_farrell · 01-23-2014, 07:28 AM

How did you determine that your getting no spark at the coils after this shutdown?

Normally things don't mysteriously fail one minute (or 10 in this case) later.

Note also to never, ever, shutdown a rotary after starting cold until it warms up.
Otherwise you will be seriously flooded. If you have a strong ignition and battery you
can restart a flooded rotary after about 4 cranks, otherwise deflood by removing plugs,
cleaning, drying and crank with out plugs to clear out the chambers.

Also note that when the plugs are flooded its like a short to ground for the spark so there
won't be any indication of spark.

well we pulled the wires coming off the ign coils and had my friend turn the key. no spark at all when i tried to arc it. and it did warm up idleing at what sounded like 4k for 10 minutes with reving and all. motor was certainly to hot to touch with my hand. weather permiting im gonna hook one of those multimeters to everything still waiting on my other stock ign coil to come in so limited on what all i can do at this moment.

heres the plugs when i took them out and sprayed sum starter fluid and cleaned them up.

and heres setup on the ignition coils grounds are running into the wiring harness somewhere.

Whizbang · 01-23-2014, 04:43 PM

umm do you have the + on one coil going to the negative on another?

mystery · 01-23-2014, 05:40 PM

heres better picture actually its running into wiring harness the red wire is what i had to do cause the dude before me soddered the two harness wires together so i had to cut and add sum wire to make it work

Whizbang · 01-23-2014, 07:22 PM

well thats an issue. the B/W is 12v power which goes to the + of the coils.

chibikougan · 01-23-2014, 07:24 PM

Yes 1 - 2 +
