Hello all i hope someone can help me with this... this is a long story but ill try to keep it short so you keep reading...my problem is that the voltage goes crazy as soon as i test up the line from my reg/rec ....my set up right now.. all my wires are on quick connects or pig tails until i figure this out...the bike is an 1980 xs650 .i have a PMA make and model not sure,it was on bike when i got it.. 3 phase reg/rec for honda magna (new).. sparks cap..(new).dyna DC3-1 3ohm coils.(new) . 7mm leads with non resistor caps....points and condenser (new) ... right now i have disconnected the head light and tail light just to be sure i dont get any miss reads from a bad wire or short, i know this will make the voltage a little higher with no draw but i am taking that into account... i run my PMA into my 7 point 3 phase reg/rec. 3 wires from PMA into 3 wires on reg/rec.. (PMA tests all 3 leads even with 4-6 volts depending on RPM) pig tail two reds out from the reg/rec to one main power line (14 gauge) to my sparks cap then to a 20 amp fuse followed by a 15 amp kill switch followed by a 7.5 amp fuse to my coils... the two ground wires are pig tailed and run to my cap then to my rear motor mount that has been ground to metal on the engine and the frame both sides....(this line is 10 gauge) and test 0.06 ohm's when off as quick as my voltage meter gets there by touching its two leads together..and 0.06-to 0.10 when running..the bike runs great takes half a kick to start my valves are set my points are set my cam chain set timing set.... the thing is it has always burnt out head lights....and then my last set of coils went so i started checking volts, right at my reg/rec (the first connection is 3 inches from the reg) it reads a steady 12.5 - 14.8 volts as soon as i work up the line say another 3-5 inches it goes crazy by the time i work up to the cap it is unreadable because it is flashing so quick but i see 19 and i see some times a minus???? i have grounded the hell out of this bike and it does not change, the motor has a good ground to frame... i am at a loss???? bike runs great out pulls all my friends xs650's but it will keep burning up electronics if i cant fix this problem... i just cant understand how it can read the right volts at the reg and then go so wrong 3 inches away???? it seems to be feeding back the line but why??please anyone i am out of ideas.....thank you for reading this what i see has turned into a short novel.
