my 1976 244DL has been going great ever since i got it but all of a sudden the fuse for the fuel injection relay, solenoid valve and the instruments blew and the car stopped working. So i put a new fuse and it blew again i tried again and managed to get the car running for about 3 second before it died now it blows every time the key gets to position 2. the thing i did to the car before this happened was move the alternator around (because it the v-belt tensioner and i need to get the cam gear cover out to paint)but that shouldn't have affected the fuel relay stuff?
