Hey All,
oki, i have a number of toyota ignitors and there seems to be some differences between how they work...
i have a 4 wire internal that hooks up directly to the reluctor and coil, and thats all good.
i have a 4 wire external that hooks up directly to reluctor and coil and that also works. (part number: 89620-10050)
i have 2x 5 wire igniters, part numbers;
89620-12300 (48) (from 4AGE)
89620-14280 (77) (unknown, possibly 22RE?)
the wires for the 4AGE one are fine for power (orange/brown), coil (black), and reluctor (pink and white) and i'm assuming the yellow one is tach output?. oh, and the igniter case is ground.
i believe that the 4AGE one is meant to send reluctor signal to ECU then receive signal back to fire coil.
the 77, i believe was direct reluctor hook-up, no ECU intervention.
for both coils.
when hooked up directly to the reluctor, the coil doesn't fire.
disconnect the reluctor.. then ->
pink wire (to rel) has 0.6v, grounding does nothing
white wire (to rel) has 0.7V, grounding fires coil weakly.
applying a logic signal between 1 and 5V to either white or pink seperately fires coil strongly.
so, does the ECU take in the low level reluctor signal, and then send back a 0/5v logic signal to the ignitor, causing it to fire?
are there any 5 wire ignitors that hook up directly to reluctors?
am i missing something in the reluctor to igniter interface? or should it be that simple?
thanks in advance, Stewart
