I cannot find the Voltage Regulator on my1981 MCI9. I see F1 going to rear junction box terminal 48 and 49 then going to front of bus. Is mine missing or is it in a front compartment?
I have owned 5 MCIs and every one I had including my 1980 MC-9 was in the back baggage bin right side on bulkhead. Unless a previous owner hid somewhere. Check rear engine compartment left rear and see if moved close to that junction box. Good luck. Charlie B.
I've always found them in the right rear bay also! BK
;D
Yes, MCI 9 bus regualtor in last bay blukhead wall passenger side behing a metal protective box. If your just setting the volage, you can do so without re-moving the box, just place a very small sloted screwdriver in the hole and turn a little. If the regulatory is not working. you can just replace the circut board for around $75 and 4 screws. easy to do.
