Borg Warner ABS 101 Sensor about $25 bucks
at Pep Boys. Works better than the Mazda
ignition pick up. Very narrow well formed
pulse due to the rectangular pole piece.
Plus minus 20 volts. Way more than enough.
If you are having trouble with the Mazda
part try one of these.

Hi Paul

Sorry about the HMTL,

Thank you for the data sheet on the power transistor.

I think you may have missed my suggestion for using abs wheel sensor for
ignition pick ups try ThePartsBin.com it's common one made by Delphi the
part no. W0133-1630340  for $17.95 it's not worth making them and if one
goes down there cheap enough to carry in your get me home kit.

In the UK we have eurospares that list a similar common sensor similar
price.

No I remembered and that is why I went to Pep boys.
Thanks and it worked like a charm.

The 555 system is getting cheaper all the time :)
