That's the one, measure at the violet/green wire in female connector (which goes to the sensor) an ground.

Ok when I'm getting 3.5 there when my black lead is on 31 (ground) in the relay socket if thats where it's supposed to go.

Then do the same at the male part, the connection should be open.

SeanK75 · « **Reply #28 on:** February 22, 2015, 05:52:03 PM »

I'm getting no reading from the male pin to 31 on the relay.

SeanK75 · « **Reply #29 on:** February 22, 2015, 05:55:26 PM »

What do you mean by the connection should be open? The sensor is plugged in, the engine/chassis and relay are not. Yhanks

Then it looks normal, reconnect the chassis/engine connector and measure again between 31 and E in
the relay socket.

Ok it reads 3.5.

Inge K. · « **Reply #32 on:** February 22, 2015, 06:06:29 PM »

Try also to measure between 15 and A2 at the relay.

SeanK75 · « **Reply #33 on:** February 22, 2015, 06:06:48 PM »

So I seems like the temp sensor is fine. But when I turn the ignition on the fan still comes on. Can I trace it from the fan? What else could be signaling the fan? A fault maybe? Something that won't allow my bike to start. Any ideas? Horn and fan fuse seem to blow, maybe the circuits are touching somewhere because when I remove the horn fuse the fan doesn't run with the ignition.

1.5 between A2 and 15.

1.5 between A2 and 15.

And you measure on the terminals at the relay?....with the relay disconnected.

SeanK75 · « **Reply #36 on:** February 22, 2015, 06:19:44 PM »

Yes on the relay socket, A2(fan motor ) to 15(fuse #7)

Inge K. · « **Reply #37 on:** February 22, 2015, 06:21:29 PM »

Not in the relay socket, but the relay itself.

SeanK75 · « **Reply #38 on:** February 22, 2015, 06:25:35 PM »

No reading from A2 to 15 on the relay. Only from 31 to E on the relay, 3.5

No reading from A2 to 15 on the relay.

This is normal, it was just to check that the contacts wasn't welded closed.

Only from 31 to E on the relay, 3.5

what a coincidence, same value as in the socket.

SeanK75 · « **Reply #40 on:** February 22, 2015, 06:36:18 PM »

I'm not sure what that means. Is 3.5 not normal for the relay?

SeanK75 · « **Reply #41 on:** February 22, 2015, 06:38:32 PM »

Also reading 3.9 from 31 to 9 on the relay.

No idea, as I never have needed to measure this connection.

SeanK75 · « **Reply #43 on:** February 22, 2015, 06:54:23 PM »

Well I REALLY appreciate your time. Thanks for your help. I'm stumped so I guess the next step is taking it in to my mechanic, unless you have any other ideas.

Inge K. · « **Reply #44 on:** February 22, 2015, 07:00:55 PM »

Have you tried what I suggested earlier in this thread....with a temporary wire between 31 in the socket
and the battery negative terminal?

SeanK75 · « **Reply #45 on:** February 22, 2015, 07:04:32 PM »

I'll try now, sorry I missed that. I need to have the relay off to put the wire in, so what do I do once the wire is run?

Inge K. · « **Reply #46 on:** February 22, 2015, 07:09:17 PM »

Twist the copper strands and push it up from the bottom of the socket so it makes contact with the
connector inside the socket, the relay must be present.

SeanK75 · « **Reply #47 on:** February 22, 2015, 07:14:36 PM »

Just tried and still the fan is on.

Inge K. · « **Reply #48 on:** February 22, 2015, 07:16:40 PM »

Then I haven't any further ideas.

SeanK75 · « **Reply #49 on:** February 22, 2015, 07:19:14 PM »

I should mention that the ecu is still disconnected. Not sure that matters as the fan still comes on at ignition.
