indicators & horn not working on scrambler project

[almiester3]

Hi all, i've sorted most of the wiring on my abandoned scrambler project i picked but the indicators & horn are dead. i've not touched any wiring on the circuit
except to test continuity & the connector down from the handle bar switch block are ok,the wiring at the back has been chopped about abit & i'm thinking maybe its missing a ground connection?

If you know how to test continuity, it shouldn't be too difficult troubleshooting by following a wiring diagram. It looks like you have a 2004+ F-model, similar to mine.

See the attached diagram that I've lifted from the manual.

I've made it big on purpose. Save the image to a local drive to read and zoom at your leisure.

thanks, better wiring diagram than i found. think i'll splice in a ground on the rear indicators & see if that sorts it

Remember, if you've upgraded to LED indicators, then you'll have to get a new indicator "relay" made for LED's.

If it's like my '05, the factory horn was not wired to ground, but had a + and a - lead of it's own, and the minus went through the horn switch... which should be checked. Reason, my horn was really, really weak, but fine when connected directly to 12V. It's the horn switch that was the problem.

Yea suzuki is rather unique in that aspect. Most hondas of the 80's have the switch push the wire to the handle bar grounding it. Suzuki connects the 2 positive leads to let current flow to the horn, the ground is already there. What's switched in the 12V - I think. Its been eons since I opened that assembly.
Cool.
