Temp relay problems?
« on: December 06, 2017, 04:25:19 AM »
Well guys i got the project running but I noticed that the fan is not turning on, i had the bike on idle for 15 minuets and the fan dosent turn on


I did a few test after searching on here  but wanted to doble check


I jump the bare connector on the relay socket


Jumper A2 to 45 will bypass the temp relay and the fan should start.  fan works.

[/size]Jumper A3 to ground and the overtemp light illuminate.


Now i did this test and got nothing to work, i had the relay plug in and tryed to ground it from the bottom and got nothing , is this the right way to do it?
[/size]Ground pin E will simulate overheating to the temp relay. The fan should start and the overtemp light illuminate.  Proves the temperature relay is functiona

You should jump the contacts in the socket, with the relay removed.
Check that the fan isn't seized.

I made the test on the contacts and got the fan to turn on and also the over temp light to work but with the relay on i havent seen the fan work after 15 mints idle

Im thinking the relay is bad but dont have a 100% way to check it

Last test must be done with the relay in the socket and the engine running.
