Hello, I acquired a federal signal vista SL and i'm trying to change the flash patterns but when i follow the manuals instructions to short the wire, i apply the opposite polarity and nothing happens. I may just be stupid and not doing it properly but the manual is confusing to me.
Anyone know if it could be a wiring issue or just my stupidity
