OK its running
on the 11th I had My Proff ride it then the Dept Head then He Drove it to the Dean's office and the Dean rode it .. This makes me very Happy
While My Proff was Driving we saw Officer Stigler whom was rather excited about it ..
On the 12th I got the old lady to run !
Here is how I got the ALT to excite !!
OFF the same 12V bus that feeds the starter I ran a wire From it to the input of a relay .. then that relay goes to the input of the Rotor on the ALT
this rotor then ties to GND .
If I need it I can also run the ALT blower fan on it too so that its on when the ALT is on .
This relay is triggerd by the ALT in the engine .... its a 2A rated one for charging the starter batt. but as there is NO starter bat It is just used as a trigger..I made a guess and reckond that at low RPMs the internal ALT wont put out enough V to Trigger the relay .. and I was right !!
under 600-800 RPM the voltage is too low to sustain the pull in needed to key on the relay .. One glitch I saw was this smaller ALT used a single diode to produce DC ( very crude ) so one issue was contact buzzing at the rate of the RPMs of the motor .. NOT good .. so I grabed a cap and just shoved it across the relay coil to smooth the DC ..... BINGO! it works .. and well!!
I may use a Op-AMP and a MOSFET to triggger it some time later to a PWM RPM sensor .. but for now its rock solid .. Yet Crude ..
