Have a question about these things..

I got 2 brand new sealed in the bag units. Figured it would be easy to wire up 4 rear lights to 1 box, and 2 front lights to another.. all halogen. Seems simple. Red power wires to 12v and 2 black wires to ground, connect the + - of the lights to the red/white wires and your off to the races... but that snot the case here

How in the F do these work? I hear no relay clicking or anything.. no voltage on the output wires either. Unit is getting power and fuse is good.. yet nothing is going on

Dip switch 1 is set with the rest in the opposite position for running 1 box (for now) and still nothing. User manual is very not helpful for this. What am i missing in this simple operation haha

That would be nothing. It was listed on ebay as a ambulance 4 output flasher unit.. So i just assumed it was a stand alone unit as it appeared as such

Just had the box wired up to 4 halogen par46 lights

You need a blink controller that’s programmed to recognize n control them. They’re not stand alone. MPC01,02 or 03

..well shit. Useless to me then. Was hoping they were just a 4 output halogen flasher unit. Mount the box in the trunk and wire the lights up to it and power via a switch and all is good.

Back to my 1st plan of using 4 head light flasher units. This is for a 1988 cop car rebuild

Need 2 rear roofbar lights and 2 rear deck lights to flash together. 2 front roof lights on their own.

Funny I have a controller but no clues what it's programmed to and don't have access to the programmer so I just use the siren and airhorn and Pa off it till I can, I have the bl627 and isp188 together on it for when it is, just independently switched now

If you request the software from Whelen they’ll send it to you for free. I built a programmer for the mpc01 for about 20 bucks... if you want to go down that route. Search for Blink programmer threads. You’ll find it here.

Good luck,
Seth

I actually did the search and my buddy is supposedly having trouble getting the rs485 part so I can program it, so still a waiting game... Ugh!!

Nevermind, gotta cut my twisted pair to jump to my 188, got it all programmed, but the 188 isn't doing what I programmed it to do. Got to check it's address.
