Thre things need fixing...

1. Hazard lights only flash one side - new flasher unit I guess?
2. Rear brakes uneven pull - adjust the nearside up a bit?
3. Handbrake not quite holding.  I always have this problem and it's always difficult to fix.  It works on the offside rear, which is not the one I need to adjust, I guess the cable needs to be a bit tighter but where to adjust it?

uneven brakes arent a failure on the rear of a trike, from reading the manual its my interpretation that they can only fail for brake imbalance on the steered wheels

if its so severe that you can feel it on the road then obviously it needs sorting anyway

its worked out on weights, so if your trike is light then that helps.

weight dose not come in to the breaks anymore they just have to lock up

they used a brake tester for mine, a big g-ball that fitted between his legs then he took it for a rip. he said the handbrake just met the requirement but couldnt tell which side was better, (the right locks the left doesnt) he said is doesnt matter if one side doesnt work as long as it meets requirement, so i asked why i need a hand brake on each wheel, he stood there blank

I'm so used to it I compensate!  But you're right, it does need sorting.

That'll be a bugger then, might have to take it somewhere.

Took it to a bike mechanic in our club, the problem was in the switch, didn't really understand but obviously he did.  What I did understand was what he said about the way it was wired - the live feed went to the flasher unit first, then to the switch, which didn't make sense to him or me.  Went to collect it and all was working fine.  Off I went down the road, indicated right at the end of the road, still fine.  Went to indicate left at the next junction and everything went wrong!  Turned on the indicator and all that happened was all the indicators flashing just a tiny bit.

Went back to Pete's and we scratched our heads a bit and he found a solution to make the indicators work - he cut one of the wires from the flasher unit to the indicator!  So I currently have working indicators but not working hazards, which suited me fine as it was 8pm by then and I'd had no tea!  To be fair to Pete, he was out of his comfort zone cos he's only ever worked on bikes.

Any way, did a search on here for threads about hazerds on trikes and emailed them to him, he thinks he's figured it out and will get back to me when he's got what's needed.  He did sort the handbrake though, works a treat now!

im in no way electrically minded and t-bone talked me through the a complete new loom for my trike. but the hazzards i couldnt get my head around,so i brought a hazzard kit off of ebay, a simple couple of wires to join easy even for me and they worked Grin think it was £10 comes all neatly heat wraped, may be an easier option gran if you have to pay labour etc maybe cheeper too Smiley

That`s the correct way to do it. The function of the switch is to direct the  feed either to the left or to the right which completes the circuit and allows the current to flow.

Yep, we both understand it now!  And it works!  

What we don't understand is why it worked at all the way he did it first, but heyho, that's electricfs for you!  Was a good job I had to take it back as it happens as he noticed the brake light wasn't working for the rear brake - the spring on the switch has got very weak so he modified it a bit!  Think I must get another spring tho cos it's done this before.  

MOT 0800 tomorrow - wish me luck cos I want to go to a rally on Friday!
