On the Starter Contactor the 2 large studs aren't marked in any way. Am I therefore safe in deducing that it doesn't matter which one I attach to the battery input and starter motor? The third smaller stud connects to the push-to-start button. The more questions I ask, the more I learn and the less I need to ask! Many thanks in advance.

Electrical current can flow in either direction thru the contacts of the contactor (switch).

Last night I installed the B & C 1.5 A dimmer which went off as described in the instructions. After adding power, my panel dimmed as expected but the dimmer knob control (rheostat) seems to have very limited variability. Turning the knob all the way left turns off the panel lights as expected. Turning it very slowly for the first 1/8 inch turns the lights from completely off to everything in between and then full on. How can I modify the sensitivity such that the dimming effect works throughout the full range of the dimmer switch?

Nevertheless, when I tested it at night (still at my garage) I noticed that there are a couple of instruments (e.g. the Trutrak ADI) which have a brighter light than the others, and obviously the single dimmer, operating all lights simultaneously, doesn't get me an optimal dimming position for all lights at the same time. Is there a trick to obtain similar brightness in all lights? Can that be achieved by simply installing resistors in the brighter ones?

Adamson Sent: Thursday, June 26, 2008 9:23 PM Subject: AeroElectric-List: EL Lighting Ok, so the docs on the UMA EL lighting says to twist the wires on the AC wiring for 8 turns per inch... Ok, but has anyone used shielded wire? I'm wondering if there is an advantage to using a 2 conductor shielded tefzel wire (which is twisted internally) and then just ground the shield at one end. Will it be any better or worse than just twisting the 2 wires - unshielded that UMA gives you? For those that don't know, the EL lights use AC (around 100V) to cause the lights to glow, it's low current, but AC and I'd just as soon limit any source for Hmmmmmmmm... Thots?

If you're only driving LED's and the dimmer circuit was designed to support incandescent bulbs, I could see this happening. It could be something as simple as being at the end of the range for the potentiometer (the thing the knob is controlling) in the dimmer circuit. If this is the case, you might swap the pot for one with a more appropriate range (lower peak resistance). Or possibly you can put a bypass resistor across the pot - while still getting adequately dark. Or, swap out some of those super efficient LED's for a couple of hog-heater light bulbs. :) You could talk with B&C about what to do - product support.. It would be a bit surprising if they haven't run into this before.

I am using the Z13/8 with SD8 self excitation. I thought I had checked all the suspects and eliminated them one by one as the problem . So as a final step I figured the battery itself was bad. So I recharged a nd disconnected the ground from the firewall. Let it set and wouldn't ya kn ow it. It maintained a charge. So back to the drawing board. In checking al l the possible problems again I noted that that SD8 self excitation may be the problem. I have connected the ground back to the battery and the firewa ll. Will wait to see if it draws down again. With that said who is using the SD8 with self excitation as pre Z25. And if so any problems....... Being tech. challenged in this stuff I am not quite sure how to check the S D8 wiring to find the problem if in fact it is. If the battery discharges w ith the SD8 as configured then maybe it is the problem. I will recharge the battery and disconnect the SD8 from the battery contactor and see what hap pens. If the battery maintains charge with the SD8 removed I will know that the SD8 is the problem if not....................????????
