satansmeerkat Posted March 28, 2015 Share Posted March 28, 2015 Hi guys,I have finally got my xv 535 running, and now just need to sort the fuel pump. The live wire between the pump and relay is dead. The question is, does the pump always run when the ignition is on, just when the ignition is running, or is it regulated somehow by the carb?I cant seem to find the source of the problem, if the pump is always on with the ignition or engine running then I'm going to put a switch on the sidecasing and bypass the relay all together. If not, then how do I fix it?Cheers peoples Quote Link to comment Share on other sites More sharing options...
eastanglianbiker Posted March 28, 2015 Share Posted March 28, 2015 To check if pump us running pull fuel line off carb and into a can turn ign on and see if it pumps as it's not continuously running when onto carbs Quote Link to comment Share on other sites More sharing options...
satansmeerkat Posted March 29, 2015 Author Share Posted March 29, 2015 Nah, I know it works, I've done that already when I touch the live from the pump straight to the live on the battery with another piece of wire. I need to know if the pump is regulated by the relay. I think it is because of the terminology in the Haynes manual.I was wondering if I could bypass the entire relay system by putting a manual switch from the pump to the battery, and mount the switch onto my side casing, below the seat, and just flick it on whenever I ride. Though, if it is regulated by the relay then the carbs would flood because the pump would be on constantly. Quote Link to comment Share on other sites More sharing options...
Tango Posted March 29, 2015 Share Posted March 29, 2015 Yeah.....I wouldn't be bypassing the fuel pump relay mate.......if it's faulty replace it...... Quote Link to comment Share on other sites More sharing options...
Stu Posted March 29, 2015 Share Posted March 29, 2015 I would look at fixing the issue and not bypassing it have you tested the relay? Quote Link to comment Share on other sites More sharing options...
Tango Posted March 29, 2015 Share Posted March 29, 2015 Dunno on that bike, but a lot of bikes with a fuel pump have a tilt switch that kills power to the pump in the event of a drop.....so maybe check that out too if it has one.... Quote Link to comment Share on other sites More sharing options...
satansmeerkat Posted March 30, 2015 Author Share Posted March 30, 2015 I'll look about tomorrow for a spare relay at the local bike shops and garages Quote Link to comment Share on other sites More sharing options...
