High Charging Voltage

I installed a electronic ignition conversion kit from Mancini Racing. I noticed when the engine is cold (fast idle), the system is charging at 18 volts. When the idle comes down, it charges at 15 volts. Before the conversion it was charging a little under 14 volts. I grounded the ECU directly to a ground from the battery. If I need to change the voltage regulator should I go to source like Classic Industries, Year One, etc. or go to an auto parts store. Thanks.

The electronic ignition conversion should not have any effect on your charging system assuming you wired it as per the instructions. This sounds like a voltage regulator (VR) issue. Up to you where you get one but personally I would source it locally, much easier to return when it goes bad or doesn't work. IMO they are all made pretty much in the same place, however some do have better QC than others (NAPA..) and there is a guy online that has an adjustable VR. I get mine at the local O'Reillys.

I thought I had an over charging problem once. Turned out to be the adjustable voltage meter. Checked at the battery with a multimeter and adjusted the voltage meter accordingly.

I followed the installation exactly. I'll check with the local O'Reilly. Thanks

I checked it at the battery, same as the voltmeter in the car. Thanks

I replaced the voltage regulator, no change.
