SAF_Capri Posted April 17, 2009 Report Posted April 17, 2009 Please help, i have no spark-so no firing up today any ideas on what can cause this would be great? ..coil?, mbe?
Fiesta Steve Posted April 17, 2009 Report Posted April 17, 2009 Could be the coil, but they rarely give probems. Check power to the coil. Check rotor arm. Check main HT lead from coil to dizzy.
bigglesmk2 Posted April 18, 2009 Report Posted April 18, 2009 After abit of head scratching i found the condensor was at fault when i couldnt get a spark
SAF_Capri Posted April 18, 2009 Author Report Posted April 18, 2009 It lives,...the mbe would only provide a spark on permanent live. as soon as you went ignition live feed it wouldnt, its an XE, 45s, MBE 912v2 and wasted spark coil pack, ... it works but if anyone has ideas on why it doesnt give a spark when wired into ignition live on a relay even tho all feeds are being provided, its as if the relay fails? i followed the sbd wiring diagram.
Admin Vista Posted April 21, 2009 Admin Report Posted April 21, 2009 bump, advice needed Ummm ummm ummm Have you thought about fitting a pinto? Sorry mate, not my strong point ignition systems, free bump though.
SAF_Capri Posted April 21, 2009 Author Report Posted April 21, 2009 its purely when its on ignition live through a relay--i checked the relay, it works and with ignition on first click power is on in all the right places, but when you turn the key to turn it over there is no spark
SAF_Capri Posted April 21, 2009 Author Report Posted April 21, 2009 where is this? it turns over fine, all things run of the ignition live fine, cd player, lights, hazards, etc...
capri_350 Posted April 22, 2009 Report Posted April 22, 2009 Not all the ignition lives stay powered when the engine is cranking. I think this is to stop overloading stuff when the starter motor spins, or to make sure the starter has as much juice as possible. Certain items (normally includes the stereo) will turn on when you turn the ignition on but will cut out when the key is turned further to the start position, then come back on when the key springs back. I have a feeling that from the ignition barrel there's one wire that stays live when the engine's cranked and one that doesn't.
SAF_Capri Posted April 23, 2009 Author Report Posted April 23, 2009 bet im clagged to the one that doesnt ..will have a look tomorrow and do some tests, cheers buddy
SAF_Capri Posted April 25, 2009 Author Report Posted April 25, 2009 Going round in circles!!...ive found the wire for the coil, and using that to power the 'ignition' feed to the relay for the mbe, HOWEVER....when switching off the ignition the engine keeps running!! ive found that a small amount of power is still remaining from the cable, thus keeping the mbe going! ...please help, i need to get rid of this residual power, but how? please help, shane
RUSTYPUP Posted April 26, 2009 Report Posted April 26, 2009 Is your original problem due to the ballast resistor? If Capris have them?
SAF_Capri Posted April 26, 2009 Author Report Posted April 26, 2009 its becasue of the voltage/amps remaining in the cable, but how to i stop it happening?
