Speedo wiring loom - 2003 kawasaki VN 1500 Vulcan Classic Tourer - Fi

Che ck for the broken wire in the front loom.

sounds like a ground problem. look for where the wire loom is grounded to the frame. it's probably loose.

The tach wire will be a pink wire under the wire loom leading up to your speedo. It's usually tucked into the conduit. If you don't have it there, then you'll have to run one all the way to the ECM.

Check the printed plastic circuit connection where the loom clips onto the speedo head, they can be a source of a short circuit .

Library is the best place ever, take a pocket full of change and you can make copies of the pages you need from Chilton's Ref Books

Probably a break inside wiring loom of one/more of the three wires that eventually connect to the speed sensor on top of gearbox. The break I fixed in my 2003 Leon 1.6SX was in the loom under battery tray. My symptoms were no speedo working, and erratic fuel guage (particulary when under 1/2 full). I repaired one broken wire.

Hi,
Just check the connection on the speedo sensor and the wiring that leads up till it gets to the main loom. There could be a loose connection there.

If thats ok then you will need to get the loom checked and the dash. It could be the dash is faulty..

Thanks

Had this problem on mine & the main dealer were stumped. Eventually found it myself after a lot of pocking about.Have a look at the wiring loom in the engine compartment. Looking under the bonnet look closely on the right hand side of the engine above the gearbox where the wiring loom passes from the rear of the engine over a metal bracket/support to the front. The loom has a tendancy to rub against the bracket and eventually damage the cables within. You will have to remove the air filter canistor & a few air hoses to get to the bracket. Good luck!

there are 2 things. if the starter doesnot work you you have to bridge the wires that go to the start isolation switch this is in the loome that hold the reversing lights, starter isolator and speedo, it is very important to have the speedo connected or the computer thinks you are dead reving and leans you fuel mixtures, the best way is to get the corect harnass, have fun
