Re: 41 clipper with no spark

Welcome. That looks a nice car you are going to be playing with.

You can bend the tabs or twist the end and remove the armored cable entrance "can" at the base of the coil to expose the power terminal. If you have 6v when the key is on most likely the ign switch is OK. The wire inside the armored cable can be prone to deteriorating insulation -- but that is usually an intermittent condition and you should notice it by a heavy current draw.

The usual oxidation of the points or terminals and having a good ground at the distributor would be worth checking after sitting so long.

One other thing is the condition of the battery, cables and terminal connections. Battery needs to be in good full charge condition and if the cables have been replaced, they need to be large -- 0 or 2/0 gauge is recommended for 6v. If anything is deficient in that area then the load of the starting motor could be enough that voltage to the coil drops below the point a reliable spark can be obtained.
