1972 911Te STOPPED!

[jaymatwhit]

Hi all, wonder if you can help me - again!

Out yesterday gorgeous blue sky and sun, cars running great then just pops and stops. Have fuel and turns over but no spark so get towed home and have a spare CDS unit that I put on but still does not have spark.

Check for spark from coil ht to dizzy, none so im thinking it must be the coil - phew that wont cost much then.

Phone Porsche parts today - £125.00 + VAT!!! Does anybody know where else I can try for a Ignition Voltage Transformer (coil) part 901 602 502 00 or if it could be anything else?

Many Thanks - Jay

As for a second opinion, might be worth calling Russell Lewis (911 PCGB Tech advice - on 01428 602 911 - he runs RSR engineering) . . . I hate electrics.

do you ( sorry I am a 912 owner so don't shoot me if I am talking Crap ) have a pertronics fitted to the Dissy..

If so I recon it's just gone pop on you.. Rip it out put the points back in and fire her up...

Let me know if it is this you can buy me a beer and I can tell you how I knew...[]

I had something very similar on my 2.7RS - driving along merilly and as I slowed to allow someone out of a junction, BANG, then cut out. Wouldn't restart.

Pulled over, waited three or so minutes - restarted. Made it to the filling station - as I left, BANG, then power died and wouldn't restart.

AutoFarm sent me a replacement CDI - but this didn't cure the problem - car went down to Oxford were they then diagnosed the problem as the throttle 'overrun' microswitch - located above the throttle switch.

Ever since being replaced she runs sweetly.

Hi Jay,

Have you checked that you haven't got a short across the points? Its quite common to get small metalic particles stuck between the contacts. You have probably already done this but try triggering the CDI by removing the contact breaker lead from the dizzy connection and intermittently shorting the lead to ground. Be careful though you can get quite a belt from the CDI HT output!!

Simon.
