I have v90-130polini and have fitted beedspeed ducati 12 v ignition and in shed for a few months it worked fine , now i have never driven it, the regulator has burned out, all earths were connected? so got another regulator, everything seemed fine, drove round village, got back to shed and regulator had burned out again, all wires are connected? any ideas, dont want to fit another reg, until i find problem

new stator so probs not rust got into laminates so rule that out ,gives weird effects . so either 2 duff regs in a row , where ya getting them from ,as the cheapys can be shit . wrongly wired up but that would blow bulbs too , its important theres a good earth on reg box body aswell as the earth terminal . other suspects a dead short somewhere in loom drawing excess power through reg box . youve gone 12 volt electronic ,what was it before , 6 volt points . as if you havent altered loom an brakelight switch that could be ya problem .H

I THINK VOLTAGE REGULATORS HAVE TO GET RID OF HEAT , DUMP excess TO EARTH SO CHEAP NON METAL FINNED TYPE MIGHT BE AN ISSUE, FROM WHAT I BELIEVE, ( could be wrong ). Just had a look online , could be that it needs a heat sink if the coil is pushing out too much. from what i can see 1 watt runs at 50c as the watts go up so does the heat. you can boil water off a regulator as over 100c. worth checking, also measure what ac voltage is coming out of that coil when running.
