No Indicators

dont need a new fuse in using you multi meter take you indi bulbs, disconnected the plug behind the fairing/headlight and connect the probes of you multi meter to the connections of the bulbs there should be no resistance (no circuit being made) if there is a reading on your meter something is making contact with earth, but you will need some new fuses soon anyway

Gotcha- cheers. Will have a look after work tomorrow.

Hi,

In addition to the above, I think I'm going to get the switchgear off and test the wiring there in the (relative) comfort of my own home- rather than blindly replace it in the hope it'll solve the problem- that sort of activity can be expensive!-

In the event that some wiring needs to be replaced, which ampage wire should I use? The fuse is 15a but judging by the wire that's there and the 17 amp wire I've got indoors, I'd guess it's less than this.

i use 1mm stranded thin wall and i have never had any problems, i used it for the ignition on a bike for a few weeks while waiting for some bigger to arrive and had no trouble.

Just because you did doesn't mean that is a good idea

its fine for lighting not the ignition, i know that.
1mm thin wall is about 16/17 amps i think and fused to 15a means it will do the indicators

Halfords only seem to do 5,8,10 and 17 amp wire. I'm assuming it'll be somewhere between 5 and 15?

indicators 21W

P = IV 21 = I x 12 I = 21/12 = 1.75A per lamp or 3.5A going through switch.

if it uses a 15 amp fuse the cable should last longer than the fuse so you would need the 17 amp stuff.

So yc it should be on a 5amp fuse with 0.5mm cable then

Wow- the 17a wire Halfords do is HUGE! Seems much bulkier than the wire on the loom.

Chris- does that not just cover 2 of the lamps? Surely, as there are 4 lamps, it'd be 7a? Though I suppose only 1 side's going at a time...
