Hello and welcome to JustAnswer!

It sounds as if part of the vehicle may have been left ungrounded after replacing the strap. If the engine is still grounded but chassis is not then that would explain the symptoms.

What is the exact location of the new ground and what was the reason for installing it?
Was an old strap or cable removed? What was it's exact location?
