changing alternator on bobcat m610

[Anonymous-0]

I am in the process of changing to a one post delco with the regulator built in. I have to run a wire to the battery post to energise the alternator. will it hurt if this wire stays hot all the time, even when switched off I am changing a m610 bobcat.

No , you need a switch of some kind, and maybe a diode inline too. Search the 8n-Ford board for "Bob's Elect Diagrams" , thats the info you want......

If it is, in fact, a "one-wire alternator" the main output terminal CAN be connected directly to the battery AND remain "hot" at all times, even when the engine is "OFF". NO switch or diode is needed. A chunk of appropriate fusible link wire spliced in at the battery end of the charging wire is a GOOD idea, though!

Having done scores of conversions at my place we always fitted a warning light on the dash,run one light wire from #2 terminal of the ignition switch to one side of an insulated warning lamp 3w or the like,run another wire from the other side of the lamp to the #1 terminal on the alternator,the main cable is always hot when the battery is connected,when you switch on power is sent to one side of the warning lamp,ground is made through the other wire and the brushes in the alternator,when the engine starts the alternator starts to produce power the ground is broken and the light goes out,if the belt breaks or the alternator is not charging the ground is remade and the light comes on,simple,the main power cable for the alternator output usually is connected to the same terminal as the main battery cable on the starter motor solenoid.
