turn signal problem now general problem

i just want my 93 flhtc back the way it was!

testing the turn signals by the shop manual indicated a new turn signal module was needed. after discovering the BIG bucks involved, i tried an alternate plan.

with a 12v flasher in series between pins 4 and 8; 6 and 10, i got about 5 flashes per side before i heard a loud CLICK and the dash lights went off then came back on.

doing the same test as before gave the same result, indicating a new TSM is needed. now, however, before any lights come on, there is that click again. same as when i turn on the ignition switch without anything plugged into the TSM connector. so, no lights connected, CLICK when switch is turned to ON.

i did get a new TSM. when plugged in, loud click and no left turn signals and no 4 way flasher. it would seem that a short circuit would cause the circuit breaker to continually trip and reset. also, there is no power outage when i hear the click.

any ideas?

did you lowered your bike ? maybe this will help . test the wire from the rear turn signal to the harness ,underneath the seat make sure to check all the wires. if it's shorted. broken wire under the fender if nothing. go get the book , trace it by using wiring diagram . looks like it was shorted somewhere .good luck

you may have rubbed the insulation off the wires under your rear fender allowing them to short out. i don't know if you lowered your bike, but that can be a problem. it's worth a look anyway. sounds like it's flipping a circuit breaker.

One way to trouble shoot for a short up under your fender is to use an auxillary wire... connect one end to the signal and run it up to the breaker and try the system. Do this for each wire from the rear lights up to the breaker.

problem solved. operator error!

let the eye rolling begin!

i had a friend over to help me track down the "clicking" sound from my bike. it turned out to be NOT a breaker tripping but rather my speakers making a snap as the power came on. the volume was all the way down so it was just them moving slightly.

TY for all the suggestions. looks like all i need now is to figure out a cheap bypass to use a traditional flasher or buy the one from HD.

If your bike is basically the same as my 1990 the click you heard is probably a thermal cut-out. There are no fuses, otherwise you would have blown one of them and it would be more obvious. What has probably happened is your installation of a different TSM has caused a short-circuit, hence over-heated the cutout. Try a different solution!
