Hi there I have done an engine transplant basically have a mk2 fiesta
Pop plus which had an ohv engine in it now has an 1.6 efi engine out of
An xr3i the car runs/drives/sounds spot on but the problem is I'm out
Of Ideas on the charging side of things if you start the car up put the multi-meter across the battery you will see the voltage drop until it cuts out as its not able to run the fuel pump, if you rev it the alternator will start charging to 13.52 volts then will drop again its had a new alternator so that's ok and the wiring all seems okay but there must be a fault somewhere :s pulling my hair out at this point can't think anymore so any help or advice mucho appreciated,

Cheers mike
