high winder Posted February 23 Report Share Posted February 23 My turn signals work unless my headlights are on, then they don’t. is this a bad flasher or more likely a short in a ground somewhere Quote Link to comment
datzenmike Posted February 23 Report Share Posted February 23 A 'short' would blow a fuse. Voltage is lower with the headlights on and this will affect the flasher. It shouldn't lower that much to affect the flasher. Try a new one. If not that then check your charging system. . 1 Quote Link to comment

The way the B210 fuse box is setup for the headlights frankly sucks. That circuit is always overloaded and often destroys the fuse box. It can easily draw the voltage low enough to work funny for an older flasher (i.e., an old grumpy bimetallic one that takes a bit more current to kickover due to age). Put in a two relay setup where the headlight circuit just turns on the relays for hi/lo and not only will you have brighter headlights, but no risk of burning yourself on the fuse (ask me how I know), and the flasher will likely work again.

high winder Posted February 23 Author Report Share Posted February 23 So 1 relay for the low beams and another for the high beams ? also how does a relay keep the voltage up vs. just the fuse block Quote Link to comment
datzenmike Posted February 23 Report Share Posted February 23 The flasher requires the current flow from one front and one rear turn signal bulb to work. If a bulb is burned out it stops. If the charging is low or engine off it flashes slower or can stop. Normally this does not happen so replace the flasher, it's the easiest and cheapest thing to do. If it improves you're done. If no change then the voltage supplied by the battery for some reason is too low to allow the flasher to work. For the battery to be that low you would notice other problems so I'm betting it's the flasher. BTW there are electronic flashers for a bit more money. They do not require a minimum current load and flash regardless if a bulb is burned out. Quote Link to comment
high winder Posted February 23 Author Report Share Posted February 23 Got it, picking up a new flasher after work so hopefully it’s a simple fix. then it’s on to a dead socket on one license plate light Quote Link to comment
