When in doubt, seek the counsel of a certificated mechanic. This is clearly not an aircraft quality device but a cheap Taiwanese knock-off.First, we want you to understand that timing magnetos doesn’t fall under the heading of “preventive maintenance.” For certificated aircraft, this is A&P country - especially if the magnetos are to be removed from the engine.However, nothing prevents you from checking timing as long as you are simply performing an inspection, and make no adjustments or disconnect anything without being under the watchful eye of your trusty A&P.Simple timing changes are neither complex nor difficult, and knowing that the spark plugs are firing the fuel-air mixture at the proper time goes a long way toward getting the most from the avgas you buy, as well as helping to prevent detonation and ensuring a long TBO run.It should be noted, though, that improper application of these timing procedures could cause severe engine damage in the form of detonation, rough running, loss in power, and complete failure. I would never have bought this device if I understood this built-in obsolescence. Except, except.they do not provide any name/address/contact means to do this! If the batteries go bad, which they will, you must attempt to send this back to the manufacturer for repair. The fact they dont have this on this unit is just wrong. This is not an ELT or aircraft avionic where someone is going to get hurt.Įvery other electronic device on the planet lets you check/change the batteries via an external access (so you dont take a chance on damaging the electronics). However the idea of not allowing the user to check the AA batteries and replace if corroded/burnt out is absurd. I think Ive got it working again after using a toothbrush and white vinegar. So, I decided to open it up (and void the warranty) to discover all 4 batteries had corroded so badly they dripped corrosion all over the circuit board and inner casing, as well as the battery compartment.
In order to inspect the batteries you have to unscrew the main casing where the circuit board is located. I purchased last February but never used it at the time.Īfter 8 months in the hangar I went to use this and I could see white corrosion along the seams. Also not happy about the 4 AA batteries that you are not allowed to replace because you will void the warranty.
