problem #1
I have LED bulbs to put in the turn signals when I put them in the sockets they don't work.
The 1157 work on the turn but not the running lights the 1156 don't light at all .
if I hook the bulb up to any 12 volt source they work fine, I also took the socket off the bike and supplied the 12 volts to the plug on the socket also works fine.
also checked voltage in socket when on the bike 12+ volts.
the standard bulbs work fine.
LED bulbs in the trunk and fender tail lights and the little LED bulbs in the front marker lights work fine.
problem# 2
I have just installed a tire pressure monitoring system on the bike if I turn the key to on it will pick up the sensors in the wheel and give me a reading.
If I start the engine it won't give me a reading
If I start the engine and hook the unit up to a 12 volt source other then the bike it works.
I again checked all voltages.
The system will read the wheels moving or not.
I do think that these two problems are related
Let me get this straight, the oem lamps work fine. . . So when you insert the LED lamp into the holder it dont work ? But you know the LED is good by applying power to it. That would tell me the wiring is ok. the problem must be the lamps contact is not not reaching the pig tail contact. Try to find out why. Is the replacement LED lamps base the same as the OEM ? measure it from the alignment pins on both lamps to the solder contacts. If the high current from the incandecent, lights the bulbs, then there's more than enough Power available for a led.
