Double glitch

29 May

A lovely sunny day, not much on so time to put the replacement rev counter to a road test.  This was a 2nd hand item from Guzzibits.  Unfortunately I'd made a hash of gluing the stopper pin on the old one, which I carelessly broke whilst (mis)handling it on the refit of the original binacle. So the dial had got a bit messy and I couldn't bear to look at it.

Anyhow the replacement from Guzzibits (£62 including postage) got fitted last Friday.

So before I changed into leathers I thought I'd start her up to warm up a bit.  I thought wrong.  No sign of ignition on turning over.  It always fires straight away.  It did after I'd done the latest loom alterations in the headlight.   So first thing have a look in headlight, 12V at the green wire to coils.  So then had a think and remembered I'd pulled off the sidepanel where the coils are to help access the fuel pipe for strimmer top up.  Had a look and hey presto, terminal to coil dangling in space.  So got the pliers out and tightened up the spade a bit, pushed it back on, proper tight now.  Pushed the GO button and BOOM we're away!  

Got togged up, rolled the bike out.  Pressed start.  No go!!  Wheeled her back in.  Into the headlight loom for a look, as I half suspected the trouble was in the 15 pin molex connector.  So I re-jigged its route and pushed it firmly home.  Once again we have sparks! Checked the lock to lock and no loss of ignition.  So the run out was back on and duly delivered.  

Bike going well, pulling strongly.

New rev counter much more heavily damped than original.  Very smooth and steady.  Wish the speedo was the same, still tends to wander a bit

Note red line still at 8K, but top reading now 10K.  Hence 5K now at 12 oclock (4K previously).

Ready to roll again after a glitchy half hour.  As usual self inflicted the old girl has a lot to put up with from her care taker in chief.

Late Loom Final

 May 14-17

Test riode fine, but on return problem with fuse blowing when lights turned on.

Fault traced to short circuit of yellow wire tail light feed inside rear mudguard mount.  Fixed by bending connector tabs to give adequate clearance, and adding insulator to spade connector.

Also other improvements to headlight loom, replacing over thick wires and dispensing with a paperclip bridge in the process.

Also shows new diode OR gate to enable single warning light for LH and RH flashing

Clocking On

 May 9th

Follwing recent less than flattering comments on new style alloy clocks and instrument mount (bought at some expense almost ten years ago!) initiated a project to refurbish old set up.  Just to prove I can.

Initially couldn't locate the relevant parts in the junk(?) bins, but another rummage revealed the alloy fitting, light nacelle and all the old wiring.  

Sent off for some extra wiring and connectors and set about reassembly.

As per rebuild

New wiring built and ready to fit.

Refitted, as per factory 1975.

With added patina.

( Almost) all warning lights fully operational

(LB stays on when HB selected)

Generator warning now working, goes out

Indicator warning still to figure out!
