Ok, but let's talk about amps.

For sake of argument, let's say each glow plug in a two glow plug circuit draws 3 amps.

Then in a series hookup, they would need 2x their normal voltage each, but would only draw 3 amps.

In a parallel hookup, they would need only 1x normal voltage each, but the amp draw would be 6 amps.

Is this correct? Can't recall my basic Ohm's law.... []
