Spider S4 speedo and sender checking
Neew to the forum and ive read a lot of posts on this subject! The speedo has stopped working .I have checked fuse 7 and have volts to generator /sender /the cable is good.
there are three wires in sender ,black,to ground,pinkish ,constant power with ignition live anfd grey ,that seems to have about 5 volts.What should oi look for to teat the sender,is it an ac generator? and can i scope output and if so what range etc,Ive removed speedo binnacle and all seems well connected,the car has been converted from lhd to rhd,are there jumper looms that may be at fault? and i cant track down a wiring loom or test procedure
phew hope some of that makes sense
