Oil and Side Stand Light on

[xbeakerx]

i been having charging issues and now my oil and side stand liight will come on when i'm at idle. why is that?? bad ground maybe?? it goes out when i rev the engine but comes back on when i idle.

i have a 1986 GS550ES. thanks in advance.

Sounds like low oil pressure. Side stand light comes on in addition to the oil light when the pressure is low.

weird. i never knew that.

I have heard about there being a diode between the circuits for those two lights, and purpose of diode is to prevent what you are saying.

So you have two probelms:
- why is oil pressure that low at idle? Is idle speed way too low? Is oil worn out an way too thin? Probelm with oil pump?
- and why does the side stand light come on when should only be the oil light? That would be related to that diode (which I have never seen on my bike).

Sounds like the diode on my bike is shot since my side stand light comes on when the oil pressure is low. Going to have to check the electrical diagram now to try to figure that out.

it does idle a little low. i will have to check all this out. thanks...
