Weird electrical problem
-
A week ago i completely replaced my engine with a rebuilt one, i had to take the old one out and since i put everything back together the electrical system has been acting really weird. When i turn on the ignition there is no lights whatsoever, and if i bump start it it lights slightly, but when i put it in neutral and put the sidestand down it sort of activates the electrical system, it is flickering on idle, but when i rev it it almost completely stops lightning.
Any advice? When i put it back together i noticed that i had lost my starter relay thing thats located close to the battery, does this have anything to do with it?
-
Sounds like a regulator issue, is the one on the bike compatible with the engine?
-
@Bluestoesonnose yes, it started to do this when i installed the new engine, i doubt it is the regulator, and that i might have done something wrong.

I have had similar, but not identical issues, after faffing around with a rebuilt engine. Turned out the ignition switch loom had just completely corroded and was intermittent.
Trying to resolve this problem is difficult unless you know exactly what causes it. For me, it would work sometimes, ride the bike down the road and the YPVS would fail.
Once the bike was on, it was running, but the act of moving it unjarred a corroded cable.
Check to you haven't tugged one of the wires.

So you're saying you have no starter relay?
Which houses the main fuse and supplies power to the rest of the bike? I reckon you need to find that and fit it
-
@finnerz89 i mean the thing you plug into the starter relay, i dont know what its called
-
@Bananper a plug? 4 connections in it?
-
@finnerz89 yup
-
Well it's connected to the loom so it must be there somewhere lol

@finnerz89 https://mtp-racing24.com/media/image/product/16642/lg/starter-relay-solenoid-yamaha.jpg there should be something there right?
-
Yeah definitely should be a plug in there. 1 or 2 cables for the starter solenoid (to spin the starter) and then 1 or 2 for power to the rest of the bike
