Accuspark Failure

  1. I need to do this on mine, Pertronix fitted, so glad to know it can be done.
     
  2. Can certainly be done with the basic unit. Only thing to watch is that if you're rotating the crank pulley back and forth while adjusting, you need to wind it back good a bit for the Pert's Hall-effect sensor to "untrigger". Other than that, same as breakers.
     
  3. this is the main problem with inducer type modules.....there's a 'window' of sweep, during which the current will be induced...this can affect timing by a fair few degrees....I've read a few threads where people have narrowed the rotor arm tip to account for it.....is it necessary? Who knows?
     
  4. You know where you are with points. ;)

  5. Yep. At the side of the road waiting for the AA ;)

  8. And their gel-haired young'uns have never seen a distributor before...

  9. I found the Pertronix would trigger spot-on if the dissy was rotating the right way. If you tried rotating it backwards while fiddling, it took a fair old rotation for the sensor to "let go" so you could have another go.
     
  10. Ha! blown up three Accusparks in the last year, all my own fault, last one was last week while fitting a rev counter!
    But i could never get the timing right, all spot on until i refitted the vac advance then it all went to ****, refitted the points and it solved all the problems

  11. Similar thing with points, no? (maybe less so)

    Very interesting to learn that Pertronix allows static timing etc. Big plus IMO, having sworn off accuspark I'd consider it in future if/when I get fed up with points. I still like using my dwell meter though.

    In terms of serviceability I'd also be inclined to use a dizzy that's designed for points so that I can avoid having to bin the whole thing - I'm still yet to find out whether my failed accuspark dizzy is servicable - in the meantime the old 009 with points has given me no grief (so far).

    As I've said elsewhere much of the problem with these new-fangled parts is the lack of service info available - the advice on here is invaluable, but they ain't in the haynes manual when you're by the side of the road working on the bus.
     
  12. Weeeel, not really. Points open and close, the sensor in a Pert obviously takes a while to switch off if you're working things backwards. Drove me nuts until I realised what was happening. But...a Pertronix is shamelessly expensive, hence Accuspark's success I assume. You should be able to replace the module in it if you've blown it up.

  13. Zed

    Zed Gradually getting grumpier

    Static timing is unneccessary. If you have a bod to turn the key put your timing light on, press trigger, get bod to turn key. Timing light will flash just the same while you turn the distributor. As the mark approaches the correct position the engine will start.
