    EX 50 URG won't start

    I started to check the wires for power and noticed two out of three small green wires coming from one of the leads off the key switch have melted the vinyl jackets around them and are bare in some places. Lucky I noticed and turn the night switch off. Anybody have a Hitachi EX50URG or 1990s...

    EX 50 URG won't start

    Yeah I thought at first it may have been the key switch. It has always been a little slack. I would turn it and it wouldn't catch, so I would have to turn it back to off position and try again. It would catch and start on the second or third time. its always been hard to get it to make contact...

    EX 50 URG won't start

    That's right Iantraxco. I put the old Battery Relay back on with the jumper wire crossing the two large terminals. It started up no problem. No battery light on the panel. Everything works fine, when I took the jumper wire off and tried to re-start the engine it just clicked. I have cleaned all...

    EX 50 URG won't start

    I found a small Relay which Hitachi calls it a Safety Relay behind the battery tucked down under the rad just in front of the engine. This is the unit that is doing all the clicking. I thought it was the solenoid on the starter until I tested for power and discovered it was dead. I managed to...

    EX 50 URG won't start

    I put all the leads back where they were originally and added a ground wire to the other small terminal and still clicks when I turn the key to the start position. I noticed I don't have any spot lights on when I turn on the light switch.

    EX 50 URG won't start

    Ok I think I got that, reading it a second time around. Put the two wires back on the large terminals, leave the wire that came off the single lead of the old battery relay on one of the small terminal and ground the other small terminal to machine frame. Thanks Lantraxco, I'll give it a try...

    EX 50 URG won't start

    Ok, so the new battery relay was a bit different, it had two smaller terminals on the other side compared to the old one which only had one terminal. Not to hard to figure out, I took the lead off the starter side (in the picture above) and put it on one of the smaller terminals, left the one on...

    EX 50 URG won't start

    Thanks Nige and Lantraxco I started to clean the terminals from the battey to the Battery Relay and discovered the problem was with the Battery Relay. I put a jumper across the terminals and the spot lamps came on. So i bumped the starter key and the engine turned over. Tension on the...

    EX 50 URG won't start

    I thought the battery was done, the red light was very dim as I was working when i noticed it. I sat there pulling and pushing the throttle trying to make it go out, the red light flashed bright a few times but never went out. The light was very dim not bright at all as I was trying to make it...
