Project Z750 part 26

The next thing I wanted to do was check that the headlights were working.

I got my multi-meter, placed the probes into the headlight sockets (instead of the bulbs) and switched on the ignition.

Nothing.

The Z750 has two front headlights. one is dipped beam and the other is full beam, so I tried the other headlight socket.

yep, you guessed it. nothing.

So I tried each socket again, and pressed the full beam switch and the passing flash switch.

still nothing. bugger.

I went back to the two pairs of alarm wires and tried each combination of joined and separate, but still nothing.

so I made sure that the indicators were still working, and left the headlight whilst I mulled over the problem. At worst I could ride it to the bike shop so that they could fix the headlights (once the forks were back on of course).

I have done a bit of reading on how to clean brake caliper pistons, and found an article that said you could use fine wet and dry to clean corrosion off them [ http://www.motorcyclenews.com/new-rider/choosing-kit/2006/november/jan26-05-how-to-service-brake-calipers/ ]. as it suggested using 1500 grit wet and dry, I decided to be cautious and start with 3000 grit. I cut the wet and dry into strips about an inch in width. I put some wd40 onto a strip and started polishing the rear piston. After quite a while I started to notice the difference. it was getting cleaner. well, it was working, but it was going to take a long time. well, I was patient and I really didn't want to rush it and ruin the pistons. Over the next couple of weeks, I polished all of the pistons using the 3000 grit wet and dry. As it seemed it was going to take the rest of my life using 3000 grit wet and dry, I decided to take a risk and bought some 2000 grit. yep I was really pushing my luck here. I cut the 20...

I realised that this was going to be a little bit more involved than simply attaching a new battery and firing it up. I guessed that the alarm could be stopping the ignition circuit and that is when I found that the alarm remotes had non-replaceable batteries. I also read that if the alarm sits for extended periods with no power then it can be toast. So my next step was to remove the alarm. another Hmmmmm moment. I have never removed or fitted an alarm. I've never even looked into how they work and what they do, so this was quite a daunting task. I took the insulation off the cables that attach to the alarm. now we've all seen nice electrical systems with all of the different colour wires to make it easy to see what goes where, well this thatcham alarm had a very large bundle of cables and all of them were black. No help there. So I had a look at how they were wired into the bike's loom. there was a bundle of wires going to the rear, which I guessed were for the i...

The piston puller has arrived. it looks like a pair of pliers, but works opposite so that when you press the handles the "nose" of the pliers expands. the idea is that you put the nose into the piston, grip very hard and turn and pull the piston so that it comes out. the theory is great, but actually using one isn't. in use you are trying to grip as hard as you can, and at the same time trying to pull the piston out of the caliper (as well as maybe turning it if it's stuck like mine). it took a herculean effort to get one of the pistons out, I was gripping as if my life depended on it, trying to twist the piston and pull it out of the caliper. when it turned (a little) it gave me renewed hope of getting both pistons out, and eventually the piston was out, so just one more left. so now on to the fifth and final brake caliper piston. I put the piston puller tool into the caliper, gripped with all my might (no laughing please) and twisted. Well something mo...
