Hi, ive got a 86 trx350. Bought as non runner,ive put new cdi,coil,spark plug and had loom apart. Ive found that on cranking i get 90 volts out of black/white wire but a varying1-12 volts on black/yellow wire to coil/fuel pump wire but this goes down to 0 when connect to coil. All i can think is that my new cdi is faulty??? Can anyone help me please!!!
