Hi, having problems to start our Takeuchi TB108. Symptoms are as following: Turning ignition on does flicker the engine and oil pressure light and makes a clicking sound in some relay. But you can't start, lights go out if turning the key to start. Did exchange the two relays which seemed to be related (Stop Solenoid Relay and Hour Meter Relay), but his didn't changed that much! ;-( (Above relays according to: PARTS MANUAL TB108 BB5Z004-1.pdf ) If anyone has an idea what to check/measure, I'd be happy. Have knowledge about electricity (volt meter/etc. available) and being a trained car mechanic, though decades ago.
I had one with similar symptoms, check battery cable behind batteries between radiator , this one the smaller red one was buried in dirt and corroded through.
Like Overworked said. Start at the battery, or check the voltage at the back of the key switch, it will probably go to zero when you try to start it. Bad connection on the battery cable or ground. Or measure battery volts when trying to start. If the battery voltage doesn't change then there's a bad connection. Battery drops, bad battery.
Problem seems solved! Thx a bunch to overworked and Delmer. It seems indeed cable related, I moved the cables in question a bit around and the machine is up and running again! ;-) Need to dig deeper which cable is the one that needs to be exchanged, but for now I needed the machine in order to dig our pathway free, which got blocked recently, due to extremely heavy rains (might be HAARP/Chemtrail related?).
