Ammeter conversion

"There's a thread for that" LOL

Be sure to read all three pages, as it covers a number of cluster styles. I used the inexpensive "Sunpro" gauge mentioned, using the factory ammeter face. The adjustment in the new voltmeter is set so that 14V is center on the ammeter face. Thus when the system is properly running at 13.8--14.2, the needle is centered
