Dead Wing

Post by roadhawg » Wed Mar 25, 2020 4:21 pm



Went to start my 1500, turned the key on and everything was good, lights came on then I hit the starter button and it clicked and everything went dead. The Battery is fully charged, the main fuse link is good. I have removed the battery and battery box and checked the wiring to see if there is a break or loose connection, but have found nothing. I tested the starter relay and it failed. My question to ALL is; will a bad relay cause the entire electrical system to go dark?

No, a malfunctioning relay A will not cause complete loss of power. On the battery (+) side of that relay is where a 30A fuse gets power from and that connection could cause all loss of power. What relay was tested with the how and what failed exactly?

I didn't think a bad relay could possibly cause this kind of issue either, but thought I would rely on the experience of other 'wing owners. The Relay failed in my first continuity test, but I conducted it again later and found that there was continuity. To test it I connected jumper wires to the 2 terminals on the relay switch and then connected an ohmmeter to the terminals on the relay. What I have found though is that the harness connector for the relay has been hot enough that I had to use channel locks to pull it apart and think it will need to be replaced. Have checked the 30 amp fuse that is part of the connector and it isn't blown either.

Often when you hit the starter and everything goes dead, the problem is a bad connection on a battery cable - either on the terminal connecting it to the battery, the battery ground cable connection to ground, or inside one of the battery cables itself.

The connection or cable can be good enough to pass enough current to light all the lights and so on, but as soon as you hit the starter, that sudden inrush of hundreds of amps to the starter causes the iffy connection to open, and now no power gets through at all. Sometimes wiggling battery wires can get power restored, but that is a temporary fix at best.

That just happened to me a few weeks ago. Turned out to be a loose ground connection at the battery.

I have checked all of the ground connections even removing some of the faring and checking and taking apart and retightening the two main ground connections (1) on the engine and (1) on the frame, still nothing. I figured out that there are actually 2 Starter relays I performed a test to see if it would switch on and found that it will not, which leads me to assume it is bad. My brother has a late 90's ATV which he said had the same problem and after a lot of diagnosing found it to be a bad starter relay. Makes no sense that a relay would control all of the current. Unless someone knows of something different I guess I will buy a relay.

No blown fuse is not a valid test, the wiring for and around that 30A fuse holder which feeds the ignition switch has been known for heating and melting which can cause problems. Probe the red wire for voltage after the fuse.

I have seen battery terminal connections fail suddenly under high amp draws internally, where you can't fix without getting another.


When it's time!

I have as well, but usually only after the battery has been abused physically (i.e. horrendously bumpy road causing multiple hard physical shocks to it).
