Zeftronics Gen Control G1120N

Received quickly, product is as described. Fast free shipping and no problems. No time to install yet A&P has been super busy

Such.an improvement over the stock points style regulator. Seeing voltages of 13.8-14.2V consistently. I few confident running with all my lights at night now. Highly recommended.

Direct replacement for the old one, much less jumpy on the ammeter. So far so good

I have gone through 3 volatage regulators in less than 1 year. Now have Zeftronics voltage regulator and working great. Hasnt been long on yet but the others would have already quit.

works great, had quite a problem trying to check out as a guest because I do not have (or want) a nother password to remember but a phone call solved that problem, this time.

I would like to update my pervious review. The GCU was not defective the issue was in my aircrafts wiring. This GCU works very well since it has been installed with new wiring.

Easy to install as per the included installation manual. Works much better than the old relays based regulators. With the old regulator my Ammeter was all over the place. Now it is rock-steady and the current output at low RPMs (1500 RPM) is higher.

They work better than the old point type and they cost less.

Used the same bolt holes connected the wires in the same order. Works

I had this installed with a newly overhauled generator and my voltage was normal for the first few flights. I noticed on a xcountry that my volatage was 17.5 on a 14V aircraft. I called zeftronics and they were less than eager to help. They sent me via email a packet that my a&p would need to fill out to send and send to them. Well see how long this takes to trouble shoot.
