CT Enviado do meu iPhone ________________________________ Message 2 _____________________________________ Time: 02:49:26 PM PST US Subject: AeroElectric-List: Voltage Regulator Questions From: "farmrjohn" I have a Zeftronics R15V00-A regulator controlling a Hartzel/Plane Power 60 amp alternator and am trying to troubleshoot the alternator dropping off line. The regulator is connected to the alternator and bus per their wiring diagram with no indicator lamp connected to pin I. The connections utilized the existing wiring, dating to 1994 at the latest, and 1966 at the earliest (externally braid shielded wire with faston connectors for the regulator pins) and feel a bit loose on the regulator pins. The S and A wires also attach to noise suppressors. I'm considering replacing the wiring to have new faston sockets. 1. Can the regulator be wired as in the Z-11 diagram with pins S and A jumped together from the alternator switch? 2. Does the regulator need the external indicator lamp connected to function properly? 3. Do the wires to the regulator pins need to be shielded/grounded as they are now? If so, will the current jacketed/shielded wire be adequate? 4. Are the noise suppressors necessary or can they be eliminated? There is currently no alternator "whine" in the radio.

Less than gas tight electrical connections are a common issue and with loose faston connectors and an intermittent issue, perhaps a cheap test is to squeeze the fastons slightly with pliers to improve their grip. Be careful not to over do it, as theyll be too tight to put on and the temptation is to use a tapered screwdriver to open them up again, potentially misaligning the sides to the point where already limited contact area is reduced. Costs little in time and might do the trick.

No, the 2 amp fuse or circuit breaker might blow or trip when the regulator is outputting 3 or 4 amps. 2. No, I don't think the regulator would be designed to shut down when the lamp burns out. 3. No, I don't think that shielded wires are necessary. 4. Whine is usually caused by a bad diode. The capacitors are probably not doing much good. But they aren't hurting anything. So why remove them? 5. I agree with Stuart. The problem is most likely a bad connection. Make them tight. It is highly unlikely that wires are the problem. Just fix the terminations. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=506374#506374 ________________________________ Message 5 _____________________________________ Time: 08:16:01 PM PST US From: Charles Kuss Subject: Re: AeroElectric-List: Voltage Regulator Questions Along with Stewart's comments, be sure to only use the PIDG [Plastic Insul ated Diamond Grip] connectors that Bob N advocates. These are much higher q uality than the crap that is sold in auto parts stores. I've found that Way tek Wire and SteinAir usually have the best prices on these. You can differ entiate between garbage [PVC insulator and it only crimps to the bare wire] and PIDG [ uses Nylon insulation and allows you to crimp both the bare wir e and the insulation behind it. That second crimp gives the wire support so that vibration will not fracture the wire, where it enters the insulation.
