Is it the revs or the high side pressure build up that does in the compressor? Could it be as easy as using a trinary switch high side limit switch to cut out the compressor clutch? ________________________________ From: DeTomaso <detomaso-bounces@server.detomasolist.com> on behalf of Dave <davel@emspace.com> Sent: Thursday, June 9, 2016 3:28 PM To: detomaso@server.detomasolist.com Subject: Re: [DeTomaso] Hooking an MSD 6AL Rev Limiter to disengage the A/C Compressor Hey Rob A 6AL only limits the coil drive output.
