HELP!!!! Was driving around when all of a sudden my beloved vx just stopped. Had to get breakdown recovery home, where I managed to find the cause, it's fuse no.8. Everything electrical works except for alarm/immobiliser, however I have no dash lights, no digital display, speedo and rev counter stuck at 20mph & 2000 revs and car won't start??? Fuse continually blows. Is there any one that can help???? PLEASE!

Fuse 8 (7.5A) seems to feed the STACK instrument panel (speedo) and the imobilizer.. I would unplug the STACK unit completely and then replace fuse. If it does not blow try and start it.. It maybe the STACK unit that has a short... (Check any wiring you have done such as radio, remove any of your wiring that maybe at fault ... Good luck, SIMSY

a stack for sale.......

Fuse 8 feeds quite a lot.

A17 Immobiliser control unit

A13 Anti theft control unit

A 4 Multes (Z22SE)

A 5 motronic (Z20LET)

H1 Instrument

X13 Diagnostic link.



A short in any of these units or the wiring to them would blow fuse 8

Try unplugging the other items, if you can find them quickly??? Not easy, and stacks can give problems... But must be one of the above.... Car will run OK with no stack plugged in, I believe.....

Hi simsy, thanks for the advice, bang on the button. The stack unit has a short. At a cost of £1200 for a new one the ebay thread you gave was useful, just got to make sure it's the correct one for my car, apprently they differ from year to year??
Hopefully I'll back on the road soon enjoying our brief english summer

Looks like that one is from a Speedster so best check it isn't graded in KMs (and show the milage that way) The main difference is between the NA and the tubby - the NA uses a 'real' STACK, whereas the tubby has a fake version

but presumably cheaper?

Probably not, as soon as you mention the magic word 'vx220' prices have a tendancy to skyrocket

Try going to Stack directly, they might sort you out.

We have unplugged the Stack (speedo unit) and hey presto the car starts, fantastic. Except we don't want to pay £1200 for a new Stack. Stripped the Stack down and everything appears normal, as far as can be faulted without a circuit diagram. Will power up and check current being drawn by this unit, but does anybody have a spec on the Stack unit to say how much current should be drawn? I am guessing less than an Amp.
My fear/hope is that there is a fault elsewhere but it is the Stack that is pushing the fuse to cut its wrists.
