It will not start.

better picture

no smoke, but the unit is always passing 12 volt through instead of on off ect. Pertronix informed me of a way to test the unit (pictured). Yes, I disconnected everything from the negative side of coil and the condenser and points. The only wire going to negative coil is the black wire from pertronix./?????

Year is 72, Looks like original Wiring according to colors. The first one fried and I replaced the points and everything was OK. The second fried and now the points won't work either. I have tested both units with the battery and ohm meter scheme of rotating the magnet in the unit but the both stayed closed whitch I was told means they are bad.

I have blown two of these things now installing by your instructions, Got any ideas what might be wrong Carl?

The swap was fairly easy, I just had to drill 2 holes in the firewll for the wider bolt configuration on the 280 booster. Just make sure you line up the plunger to the pedal arm(not rocket science).

I am running a 280z booster in my 72 240 and it needs replacing. Is there an upside or downside to using this slightly larger booster on a stock 240. If its better I'll get another 280 booster, if not I'll go back to standard. Oh, Im also using 280z mastercylinder.
