Dud injector ??......Help

[Sandy]

The 2.4ohm injector are Peak and hold type, they are to be driven with 12
volts until the 4 amp current is reached, when that happens the driver is
supposed to reduce the voltage until the current is at 1 amp. You should
not use a low impedace injector (2.4ohm) unless you have the correct
driver. Get a 12ohm injector, they are the most common, and will only draw
about 1 amp. They require no special drivers.
