Default or ..Cannot get glow plugs on a twin lit.

Do twin plugs hooked in tandom need twice the power in the igniter. I can't get them glowing bright with a new 1.5v.

Tandem, meaning in series or in parallel? In series will take 3 volts.

Sorry I don't know much about electricity. More parallel, I think. Glow igniter attaches to a fake glow plug and the positive Y's out on two separate wires going to each plug, one ground to the engine block.

Sounds right, should work if battery is well charged. You have something like this.

A 1.2v NiCd/NiMH will not produce enough current to light two plugs in series or parallel. Each plug will draw 3A. In parallel it will need 1.2-1.5v @6A. In series it will need 2.4-3v @3A.

I ran an old twin engine awhile back - I had to use two cells and masically frankenstein a glow driver to light both plugs. Or use two regular glow drivers.

I ordered an on board glow system. Ill rig up two batteries and see if it works just so I can play with the settings.
Thanks.

I have the Electro Dynamics twin cylinder driver. It performs very well, and is easy to adjust the on/off point.
