Electrical questions

Recommended Posts

I have some questions on my electrical system. CTSW.

 

1. Alternator light comes on more and more often and lower (not idle) speeds. Noticed that it sometimes also blinks with the beacon.

 

2. Amp meter shows a fair amount of variation in a short period of time. Can go from -10 to +15 amps at the extremes, often goes from -3 to + 6.

 

3. Volt meter is pretty stable, fluctuates about 0.4 volts

 

These phenomenon were noted when only the master switch, gen switch, master avionics switch and intercom were on. No nav lights of any kind.

Hi Jim,

 

Eric's right. The majority of the time most of our electrical problems can be solved by cleaning and or just tightening all the grounds inside the cowl and inside the instrument panel on the co-pilot side. It takes about 20 mins to tighten them all.

Put a wrench on all of them. They may be hand tight, but wrench loose.

So, you guys are saying that varying meter indications is likely a ground problem and not something else? Good to know, because that is likely not too serious, just takes some time and effort running it down. I was afraid maybe it was a critical component beginning to fail.
