Ignition puzzle. Drove my Seven - 1930 with a just-rebuilt 1930-31 distributor with standard points ignition - up to the garage door and switched off. Although running perfectly before and starting easily, it would not re-start - there was no spark at the plugs.
Fitted another just-built and known-to-be-working replacement distributor but, again, no spark produced.
Fitted each of the distributors to another car - and both worked.
Put the original distributor back on.
Changed the coil—no difference.
Checked the earth of each distributor—both OK
Hot wired the coil direct to the battery—no difference
Tester showed that negative lead from coil to distributor was working.
Took HT lead that comes from coil and held it against the block while cranking the engine - sparks OK
So, neither of the distributors that work on one car, won’t on the other.
Any ideas, anyone?
