Intermittent alternator charge

Intermittent alternator charge

<HTML>First, is it possible for the noise filter to have any affect on an intermittent problem with the 60 amp altinator charging system on a 1972 182P.  Mine was built before the over-charging light was put in place.  This has been an on-going problem for at least two years.  It has been in the shop twice, and I have worked on the problem numerous times.  It almost always quits charging upon startup away from home.  Me or an FBO operator dinks with it and decide come on home and fix it at the home base.  Sometimes in-route it will kick in while cycling the alt/batt switch.  Other times it kicks in after refueling at home base upon startup to the tie-downs.  Most of the time it starts working after I replace a component and assume the problem to be fixed - only to have the problem show up again several trips later.

I have installed a rebuilt altinator, a new regulator (twice), a new alt/batt switch, both circuit breakers, and the wiring and plug for the regulator.  The only component still original is the noise filter (along with a couple of ground wires).

It sounds like I just started throwing new expensive parts at my problem, but there have been several diagnostics/testing along the way.

Any Ideas?</HTML>

Re: Intermittent alternator charge

<HTML>The single most common charging system problem is faulty/lost grounds.  Many times ground connections are just never replaced or rechecked and unseen corrosion interupts an otherwise healthy looking system.  All generator regulators and most alternator regulators must have their cases grounded in order to work.  Most gens/alts are grounded through their cases, but when you consider that many mounts are rubber shock-mounted and the only path to ground may be through a belt-tensioning arm (which is by design an adjustable bolt/threaded hole), you can see that a reliable ground is frequently lost.  Some better installations have seperate ground straps tying the case to the engine.  The engine mounts should also have bonding strips/wires tying them to the airframe.</HTML>

Re: Intermittent alternator charge

<HTML>And I forgot to mention that the easy way to check a filter (which is nothing other than a capacitor/condenser) is to disconnect it and use an analog volt/ohm meter to check resistance.  It should show an initial high resistance which falls rapidly toward zero.  (The condenser takes an initial charge from the meter but then rapidly discharges it.)  Remember that it is similar to a diode, ...it will work one way, but not the other when you check it.</HTML>

Re: Intermittent alternator charge

<HTML>Ted, we also have a C-182P that had alternator problems, always seemed to fail outbound on a cross country, never in the pattern, never on a return. Sometimes if you cycled the batt/alt switch it would kick in, sometimes not. This is what we did over 2 frustrating months. Rebuilt alternator, replaced tension arm holding alternator (we have air conditioner), rebuilt alternator, replaced battery, replaced voltage regulator, replaced battery under warranty. Been working fine for over 15 months, but we have no idea what we fixed. Really no help at all now that I reread this.
