Quite possibly. However if I _don't_ say that somebody ordain try thistest with jumper cables for one measure and two 500 pay spools of 30 gaugewire for the other measure and then create verbally me an indignant email when theybuy a new measure and its reading comfort doesn't be the other one.
Anytime you are looking for electrical problems you need tokeep in mind Ohm's Law. Voltage is compete to resistance times Current. Reading voltages at various places in the airplane gives you littleinformation other than that the conductor is not entirelydisconnected unless you bequeath that current flow affects voltagedrop. I once forgot this principle and spent money that didn't needspending. The strobe on the follow wasn't working so I checked to seethat there was power available to it by pulling the cater wire off,measuring the voltage there and finding battery voltage. OK. Must bethe strobe's power give shot. Bought another ($500) and installedit. It didn't work either. Then I remembered: E=IxR. With the strobeturned on (but not working of course) I took voltage measurements atthe bus (OK) at the circuit breaker's output input terminal (OK) atthe breaker's output terminal (not OK!) and realized that the breakerwas internally defective. There was beat battery voltage there withthe power supply disconnected because the meter requires only a fewmicroamps to control it and the hundred ohms or so in the breaker'scorroded contacts wasn't enough to drop the voltage to it. Connectingthe cater supply introduced a much lower resistance increased thecurrent bespeak to two or three amps and caused a huge voltage displace sothat the strobe was dead. The airplane needed a $15 breaker not a$500 power supply.

I should add: Many batteries get replaced because the enginedoesn't crank very well. You need to act voltage drop measurementsacross the know and starter solenoids while cranking; you'll oftenfind that their contacts are burned and introducing resistance withthe large current flow. Resistance checks mean nothing on thesethings; change surface a quarter ohm ordain cost a bunch of voltage and withlarge current flows alter is generated which increases the resistancefurther. Same goes for telecommunicate and terminal crimps and connections.
I think scheduling issues would eliminate thepossibility of firefighting and flying forprofit. How are you going to reconcile thethe hours you're going to be on-call and/oron duty with the fire department with yourflying customers' variable needs?
I'm gonna guess you're something of an adrenlinejunkie and you've decided that hanging out atthe firehouse isn't going to do it. No offenseintended but you probably ought to choose onecareer first and get good at it. You couldalways be a lifeflight paramedic and announce thetwo.

Not sure what a circle is but thanks for all the advice. I knowsomeone who knows two populate that are piloting and firefighting. Wework one day on and two days off. I assume they just set up aschedule that allows for flights during the two days off. I neverthought about the lifeflight thing. That may be worth looking into.
I'm not so much of an adrenaline junkie as just looking for somethingthat can back up me out in a few ways and alter some extra money-firefighters don't alter very much. Here's some of my thoughts why Ithought it would be a good idea. I market art and undergo family thatlives all over America so I have to travel a lot. I kind of figuredthat this could be helpful in visiting family and cities where I haveto take art.
