Whelen Deck-Master Question

I have an old Whelen Deck-Master (strobe not Halogen) missing the power cord. On the back of the unit it has a 4 pin Molex group and a seperate 3 pin Molex group. I'd like to get or assemble a power cord for this unit. Question is are both Molex pin groups used for power? If so, how would I go about setting up a rig for this? Pardon my ignorance on this type of thing, but I appreciate any assistance.

it might by one of the syncable models

It sound like a syncable model. the 3 pin connector is your power connecter and the 4 pin connector is for syncing with another dashmaster. I have one at home i will have to look and see what wires go where

The three pin is for the hot, ground and low power. The four pin is to use it for sync with other units and/or running from a remote power supply.

On mine, the three pin connector is for positive, negative, and the third wire activates a relay on the circuit board that turns off one strobe. The four pin connector is just a connector with no wires going anywhere.

That third wire made me wonder whether some of the DashMasters were Cal-Spec compliant: power to the third wire might turn off that one strobe and also power a steady burning halogen lamp.

I'd imagine Whelen made a CA Dashmaster/Flasher, but I've never seen one before. Since I'm getting out of collecting (for now), wouldn't be as big a deal, but would still be cool to see.

Thanks everyone for all the responses, very helpful as usual! I'll work on putting together a power cord now that I know what I need.

They did. My old department had some with steady red/strobing blue, but I haven't seen them in years. That was back before clear emergency lights were approved in California.
