looks like I've found a battery ( get some good recommendations) so just made a mock up and testing the position. ImageImageImage

Today Matthew I'll mostly be learning how to use a multimeter and all being well my front and rear mudguards will arrive Friday.

Hi
Good luck with the mudguards

Multimeters are easy, especially these new fangled modern autoranging digital ones

Volts are measured across two points

Amps are measured through it

Dont believe the numbers, well not to the third decimal place

Try a test lamp though, a good tool and easy to use

Keep the smoke in the boxes.

Thanks George, I started this project to learn more about how it all worked and put together and I'm definitely doing that.

hi
if you are a paid up club member IIRC I think you should be able to access an article I wrote on usung meters.

Search about the forum and read Ced's posts on using a test lamp, you can use it as a volt or Ampmeter.

DONT DO THIS AT HOME
Remember the initial method of TESTING POTENTIAL 200 YEARS AGO WAS TO GRAB THE WIRES, MORE POTENTIAL, MORE PAIN AND LOUDER THE NOISE


BT, well the Post Office, used to issue engineers with armoured gloves, a 50v shock caused them to retract their hand, often hitting the equipment rack, breaking their fingers



We taught -- it's Volts that jolt and mils that kills-- meaning large voltages jolt you but only a few milliamps can kill you
The Modern Update is that Electronic ignition has such High voltage that the Volts alone will damage you.


SO SAFETY FIRST! and enjoy the learning

Almost right George.

The gloves were more of a pad that protected the back of the hand. When working on the Main Distribution Frames (MDF), if you happened to brush the back of you hand against soldered tags when there was ringing voltage (80v RMS) applied, the involuntary action of pulling your hand away caused what was commonly called 'Tag Rash'. Furthermore the nature of the solder could cause an infection.

So another update in the cafe scrambler bike build. Due to the nightmare day on bleeding the brakes, I decided to tackle the electrics again and I'm happy to announce I finally got the beast to turn over.
I have a spark from both plugs however I still have a few small problems like the instrument lights don't work when the ignition key is at run but I'm happier than I was the other day.
Unfortunately the brakes still need to be sorted but that is a job for next week.

FINALLY got the front brake bled, and the new rear master cylinder internal have arrived so hopefully should have a fully working brake system by Sunday. Also received a package from Down&Out bikes ( mudguards) so next week will be fitting those and fabricating a cradle for the battery.
