Hey folks, new member, looking for some help with my son's Ace 250.
The other night it quit working. Everything seems to work (display, buttons, speaker) except it doesn't detect anything. I replaced the batteries, did the reset (holding power button down). It does work randomly for short periods of time - the other night it worked great for about 2 hours.
Does anyone have any suggestions? It's out of warranty but I am pretty decent with electronics repair (auto mechanic). I am suspecting it's the coil as I did some Googling and found that the coil resistance to the primary winding (pins 1 and 4) should be 4 ohms and the secondary (pins 2 and 3) 38 ohms. Pin number 5 is a shield. Could someone with an Ace 150/250 verify that is the correct values by measuring thiers? I am getting a reading of 222 ohms on the primary winding.
Thanks for any help or suggestions.
