Federal Legend troubles......

[exphillycop]

The legend on my car is driving me nuts. It works fine on mode 1 and 2,, but when it is switched to mode 3, the lights stop working. It appears to be something with the flashing alleys and takedowns. Has anyone else had this problem?....please help...

Check grounds.

What is it hook up too? Smart siren platinum? May need reprogrammed.

I checked the grounds, it is hooked up tp a whelen cencom......the SS went bad and my dept bought the whelen instead.

While reprogramming my Legend flash patterns I also encountered an issue like you are describing. All I did was disconnect the harness with the 24 wires and plug it back into the serial interface box. It went away after that. I did not figure it out...

Do the takedowns/alleys flash in mode 3 and the rest of the bar goes dark, or does nothing happen?


Does mode 3 flash if you unhook the flash takedown/alley wire? If so, does it shut off when you turn on your takedowns and alleys?


If the above does not affect operation, check the enable/cutoff wires. Dip switch one way will make them enable wires, dip switch the other way make them cut off wires. If those wires are set to enable, and tied to mode 1 and mode 2, those 2 modes must remain active when you are on mode 3.

the td/alleys flash on the passenger side. but if i hit the lightbar the lights come on. then if i turn them off then on again, same problem. also sometimes the alley lights do not activate immediately after the alley button is activated.

 

[Quentin]

Sounds like a lose ground inside the bar, how you put it

 

[exphillycop]

i'm in the car now........going to check the grounds again....thanks

 

[acs680]

I agree. Check the screws that tighten each circuit board down, as that is where they ground at. Also check where the main ground wire loops up to the main control board in the bar.

 

[exphillycop]

Just buttoned everthing down, tested it a couple times, works for now..........thanks for the help, it's grately appreciated.

 

[exphillycop]

I resecured all the grounds and it worked for a while.....now if the car is off for some time the flashing alleys and t/d on the left side do not work except for a good hit on the bar causes them to activate....I'm stumped.....

 

[Quentin]

Sounds like something else is still lose

 

[acs680]

Sounds like something else is still lose

Agreed.


I believe these are all of the ground points in the bar, but I might miss one. There is the main ground that comes in and screws down near the entrance point. From there are your individual grounds that go to each side of the bar and hook to one circuit board. The other circuit board is linked with a solid ground "strap". Since the takedowns are on a different board than the alley, and you are losing them both, check where the ground for that side comes in by the main ground, and check where it tightens to the circuit board on that side. Make sure there is no corrosion around the connection point.

Thank you guys for the info, i found that the aluminum piece that hold the boards down was broken and thats where i was loosing the ground. I removed the bracket and put 2 ground wires to the ground bolt on the bar......I hope this works. Also would i be able to get replacement brackets for my light? might as well replace the other side too

 

[Quentin]

If its Under warranty. 5 years on It and 1 year on Labor

 

[exphillycop]

I don't believe it is still under warranty, the police dept will have to just pay for them....that's all

 

[Quentin]

There you go. Tell them you want to upgrade to the new Valor! Lol

 

[exphillycop]

already had the Valor discussion.....my last car in Philly had one.....what a great light system, loved it

 

[exphillycop]

Another problem just arose with this lightbar. The left side alley and t/d light are out. I checked the fuses on the circuit board and the 15A fuse was blown, I attempted to replace it and the new one popped as well. This is a short somewhere, I checked the wires and all "looks" well. Any ideas where tis short may be?......the right side lights do work properly. All the LED are funtioning properly as well.

 

[Quentin]

I take it they are halogen? Follow the wires. Maybe you have a bad board also.

 

[exphillycop]

yes, they are halogen........this thing drives me nuts.......

 

[Quentin]

Have you talk to federal?

 

[acs680]

Is this an early model? There were some issues with the halogen lights on those. If if it is not, Federal will most likely replace the whole board anyway. They will send you a replacement, and you will mail the bad board back to keep from being billed.
