Your 1 1/2 amps is OK. You should have noted I said that the amps could be a bit lower with revs up. The point here is that the amps are not too high and four amps would be on the high side. The contacts in the distributor act as a regulator of sorts and the faster they open and close with revs up then the lower the amps current draw. Many cars I have checked with engine running are in the 2 amps or so range. If the current draw is above 4 amps then the coil windings will become hotter than desired and the points life will be reduced. Of course if you test the coil current draw with the engine not running and the points are closed the the reading will be higher. Regards, Kevin.
