WIRES WIRES EVERYWHERE.......And other bits and bobs.
So the Motor gadget M-Unit install has been completed; apart form a little final tidy up.
Following the wiring diagrams from Revival, M-Gadget & XS650 1980 from this site.
I am pleased overall that I did this job, especially considering I have never tackled a full 'from scratch' re-wire before.
Difficulties did arise such as the bar ends not accepting the M-Gadget indicator units. I had to drill out these to the maximum depth of my drill bit.
Also the M-Button had to be relocated to the center of the bars; normally placed at one end behind the indicator unit, as the M-Button captive wires were too short for my bars. More drilling and mods to the bar to accommodate this.
All cables were then run back to the M-Unit under the seat. The Motor Gadget Speedo wires back under the tank.
Got everything roughly connected up to the M-Unit for a test. Blimey everything worked as it should!
So wires were cut to final lengths and all wrapped up with nice Revival cable wrap. I did find out that the supplied 'Ferrules' for the wire ends didn't hold securely with the M-Unit ports, so reverted to bare wire which was better.
Wiring the various feeds to the M-Gadget Speedo connector block was a fiddle; especially using standard gauge auto wires. But then I found cable for security alarms, which are colored multi-strand, and cased in an insulated jacket. So things like: Neutral switch / indicators / speed sensor / high beam etc... all go through the multi-strand cable to the captive connector blocks from the M-G Speedo.
This stuff is the same thin gauge as the M-Unit Speedo wires; and makes the job easier using supplied crimp connections.
Wiring now works far more reliably and is much neater than the 'Franken-Loom' I originally had.
All good so far, just need to tidy up the M-Unit wires.
I also swapped out the old switch gear and brake fluid pots for Revival momentary switches and Billet fluid pots: again all much neater:
All good so far, except the Neutral light on the speedo is very intermittent. Check continuity from switch through the cable to the connector block and all good. Pulled switch from engine and cleaned up all seems OK. Tried a switch on again and neutral light is a no show. Could be a faulty sender switch?
OK so I hooked up a remote fuel bottle to carbs to go for a start. Motor turns over well; but no go.
Checked for sparks at the plug and.....nothing! Sod it I need to look at this but I've run out of time today.
