How does the Diesel rev counter work

dave friday The alternator produces a frequency that varies with engine speed, the rev counter measures this frequency and moves the pointer , 1000 rpm for low frequency[low engine speed] 4800rpm for high frequency[high engine speed]. From the "w" terminal on the alternator[red/black wire]it goes to e12 [fuse box in front of van] changes to green on the way! then to d19 then red/black to d26[ still on f box then b19 then green wire to t 14 terminal 9[the long connector under the dash] your problem will may be with this connector . good luck!
