Both my tacho and Mph guage dont work tacho has previously worked and mph guage never has, SVA is next week!!!
Tacho takes a feed from Edis i believe and is a ETB guage, What should i check??
MPH guage is a ETB instument one with a normall dial plus digital milage counter, has lots of dip switches on the back!! it came with 2 magnets that
are fitted to the diff??
Any help is appriciated!!
Ive just found my speedo worm drive in the gearbox is completely shorn... SVA two weeks today...... toyota dont know what part i have.... they have a few part numbers for it and dont know which is the correct one.... hmmmm stumped.
By the way..... good luck.... i hope you get there and pass first time... i doubt i will.
do ETB have a website with fitting / fault finding instructions?? if not it might be worth checking Greengauges website? What type of sender do you have ? IIRC the speedo needs a live feed , do you have one?
yea live feed to all guages on ignition- 6 work 2 dont
same earth also, ill check web, cheers
Ive been in garage sorting out little problems all day and i found that the ECU tacho out was holding at 10.3 v all the time, im lucky guage hasnt
burnt out. So i got out my EDIS drawing cause i thought that they may be a tacho out on that and scratched my head for a few munutes and found that
pin 11 was CTO (clean tacho out) and tried that and it worked- so ill get rid of the other wire.
Thats Tacho sorted- but if i had just read the above post i could have sorted it with out the head scratching.
As for the MPH guage, looks like it could just need programming on rollers or ran for 1 mile at a constant speed.
HA HA cheers mate, just the MPH guage to sort out when i drive to sva, lets hope it works!
Do you know somewhere you can acurately drive a mile and stop safely at the beginning?
If not you can work out how many pulses over a mile using diff ratio and wheel and tyre sizes.

Drove a mile in a disused wear house but had to keep speed down, it now over reads by approx 2mPH at 10mph it reads 12mph and 25 it reads 27mph, will this be ok at higher measurments??
