Unfortunately the 70A Edition uses distinct bearings than the 55A version. The drive conclusion bearing is (entrance, 021-903-221B) identified from the regular bearing component number 6303Z. It can be 47x17x14mm (od id wide) and it is metallic shielded to the entrance facet and open on the back for the reason that a canopy plate is accustomed to safe the bearing within the travel conclude protect.

They ought to be inside a couple tenths of a volt of each other. If not, there may be extreme resistance during the circuit. Several cars have a fusible website link or a significant fuse to safeguard the alternator. These is often burned up by a short or incorrect utilization of jumper cables. If there isn't a power on the alternator B+ (massive output terminal) then a foul fusible hyperlink or maxi-fuse is most likely the situation.
