Good evening all!
I've often referred to the fantastic information in the other parts of this site.. but today... I have to unfortunately hassle everyone and ask a (probably inane) question. I really should know the answer to this, but, well.. I'm having one of those days! (weeks?)
In the following schematic - what is the purpose of R1/R2 in the Rectifier Unit ? And to what degree can I (potentially) alter their values ? The BoM for this refers to 39k 2Watt MFR's.. but I can only get 1 Watters easily, so need to run some in parrallel to get the dissipation that the original author felt was neccesary.
And silly question - but how do I determine the current through the circuit when the 'source' is off an Alternator that obviously changes its generated output based on speed etc... do I just go and measure the maximum output at peak-RPM's in the existing Rect/CDI setup, or - more likely - is there some formula I've missed here ?
I really appreciate any hints, tips or feedback anyone can offer.. Thanks very much!
