Shorting the fuel pump relay query

[Zanderk]

So in the manual it advises connecting across the black and black blue terminals with a short piece of wire.

First question - could this be any wire, like 3amp, 5amp ?

Second question - I don’t have wiring colours like that on my bike, they are as follows;

I tried connecting across the same two wire positions as suggested in the manual. There’s a whirring sound and then it stops as the main fuse blows.

So obviously I’m doing something wrong but I’m not a sparky.

Any help gratefully received

I think I should be using solid copper wire and I’m overloading with my current choice. That’s my hunch.

Ok no need to reply and yep what a twonk.

Do you have the full colour wiring diagram?

Hi Chap,

I do now and I really don’t want to say what my mistake was because you are all going to lay so much crap on me But since I’m in a low ego setting I’ll tell you that I was trying to short the wrong relay !!!!! Once I had the correct diagram and then identified the correct relay all was good. I won’t tell you how many bloody fuses I’ve blown

The bike didn't go up in flames so it's okay. As a spotty teenager I remember trying to fit a new horn once and had to buy a new battery and relay when I let the blue smoke out

the shorting wire must be insulated......except for the two ends. NO PAPERCLIPS !

I have a good one that I just did a couple of months ago. This was on one of my cars. I didn't notice that the negative battery cable was black but most of it was covered with a red insulation sheath. Why they made it that way I will never know but I stupidly hooked up a battery backwards and fried my alternator.

Ive done that on the racebike. But lucky, it has not alternator.. So it just spun the gear backward. I thought i had a clutch issue, tore into that. It was hours into troubleshooting before i knew what i did.

We all have our moments.

Well you’re a generous lot, all good now and carbs back together so today I’ll see if my handywork is successful. This forum rocks though and I thank everyone for it as an ongoing resource for learners like me

I've been known to use a 12 gauge wire and it seems to hold up OK but i also usually ditch the electric fuel pump and replace it with a vacuum unit when rebuilding the fuel system. It just turns into a much easier job running the fuel line for me.

^^ but that costs money !

Yep that’s on stage 2’s list with the parts on way. Stage 1 is to get it through an MOT standard (ish) so I can register the bike as it’s an import with our authorities.

The one downside to the vacuum pump (besides the added complexity) is if you have your carbs off or drained a lot it can take a lot of cranking (keep a stout battery) to bring those babies from empty to running. They have their up sides and look very sharp when combined with a WW mount, but there is a bit of a trade off.

WW mount.........more $$$

vacuum pump+WW mount+tubing=what $
