Re: Tach for 70 AMX

[farna@xxxxxxx]

I just printed an article in the last AIM about connecting those tachs. If someone wants to scan that article and send it to Todd go ahead. I think it was in the last issue. Todd, if you don't get something from someone send me an e-mail and I'll get it to you. All late 60s/early 70s tachs are the same, but I forget exactly how they work. They are in series, I think, at least not a simple negative wire sensing hookup like more modern electric tachs.
