Buzzing from light bar?

Not sure if this is good or not but I’m in the process of wiring my light bar and their is a buzzing going on when the light is on and connected to the relay!
If I connect the light bar directly to the switch with no relay the buzzing noise from the light is greatly reduced but can still be heard if you are listening for it.
So will this buzzing cause anything? Any issue? Premature wear?
Also what is the buzzing? Resistance from the terminals or something greater?
I know their are a few electrical gurus out their that may lend their .02$

Trail boss 250 has power but not cranking

Hi, I have a 1988 trail boss 250. The Atv has power to the starter from the solenoid and has power from the key and the start button, which I’ve tested with a circuit tester. But when I press the start button nothing happens, not even a click at the solenoid.
I have recently changed the starter and solenoid hoping that they were the problem of it not starting.
I’ve put jump leads directly onto the starter and it cranks when I do that.
The cut off switch works as I’ve used it when the Atv was running from the recoil starter.
I’ve tried 2 different batteries which I know work, and that doesn’t make a difference.
Surely if everything has power to it, it must crank over?

I’m really stuck at what to do next.
If anyone has any advice that would be much appreciated.
Thanks

Trx 350 1990 – what manual?

Recently purchased 1990 trx 350. My problem is I can find almost no reference to this model – as if it never existed. My suspicion is the model is actually a 1989 carried into 1990 year. I am using 1986 to 1989 trx 350 service manual which so far seems pretty close. Can anyone confirm which service manual and model number reference (need to order a starter motor: ha7-620 or ha7-773?) before I start down the wrong path ordering parts

Thanks
