Leon - Sounds like when we solve one we'll have them both as mine initially was significantly improved by removing the vacuum. I am printing all the manual pages that relate to the EZL and will test everything I can. Mine has now progressed so it is 30 degrees with and without vacuum!
Joe - I think I tested the relay, + on 1(30) and 3(16) and - on 5(31) produces + on 2(87E), 7(87E), 6(87L) and 9?(87L). Should the outputs be regulated? (13.8 in gives 13.8 out)? The fuse closest to the cap pivot controls the power on 87E and the other 87L. The second fuse output has nothing connected to it. Sound right?
