Starter Relay Coil Resistance

[Guest]

Just recently I have been blowing my main fuse when starting the bike and I think it has something to do with the starter relay. When I checked it with my DMM the coil resistance was very low and actually made my DMM beep when I had it on the continuity setting. What should the coil resitance be? However, the ignition wire (feeding the coil) is not the one getting hot, its the +12V wire feeding into the relay.

In addition to the main fuse blowing, my ignition fuse blew once while I was out riding and I have no idea if these two issues could be related. I will be completely updating my electrical system this rainy season with a new reg/rec and relay mods so posplayr don't yell at me yet. I'm simply asking about the starter relay.

I'd inspect you wiring harness very closely. The same thing was happening to my when I first picked up my GS1000. The problem turned out to be a wire that was warn through the insulation and was rubbing on the frame. The wire bundle that was rubbing was located under the gas tank near the coils. Turned out that vibration from running or starting the engine would cause the wire to short out intermittently.

A meter beeping "continuity" only shows continuity, not a dead short. I am not sure what the resistance in the solenoid should be, but my Fluke will beep with resistances up to about 200 ohms.

I found the info in the manual 3-4 ohms

Good info, thank you. Looks like I'll be taking my gremlin search in a different direction

Interesting... it doesn't happen every time either, I'll bet you're on to something

Look for corrosion hidden in the main terminals for the positive and negative cables. The starter is a big load and corrosion can cause a huge high contact resistance amplifying the load. If the terminals have been corroded and are thin it can cause the same thing. The negative terminal attached to the transmission is the return path of the circuit for the starter motor.

The start relay in that picture is at least 50 ohm.
