I must be calling it wrong, 'cause surely I'd have burned up all my glowplugs with a six-volt hit, right?
All the positive poles are soldered together, and all the negative poles are soldered together. When I hook it up to my voltmeter, it registers right at 1.5 volts, so that must be parallel, right?
Thanx, for pointing out my mistaken terminology. (Better the wrong word than a burned out glowhead).
