Well …. yes, and no. The antenna is definitely grounded; confirmed via continuity test through the coax to the ground point. The coax also appears intact, testing from CB end to antenna base. The antenna itself was just replaced by J & M, so I presume it is also good. As for the CB itself …. no, I really don't know (but you would think that the FIFTH CB installed would be good). There is also a ground strap from the CB to the frame, so it should be grounded as well.
This was really all okay until the compressor was replaced and a damaged wire in the heated grips circuit repaired. During that repair, the CB and / or radio antenna ground was left disconnected and the J&M antenna damaged as well. So, the radio was fried by the missing ground and so was the CB by the damaged antenna … both have been replaced now (as has the entertainment harness). But, the static persists on receive …. everybody I talk to in the "CB world" says this is a ground problem.
So, here is my plan:
- Check the 8 ground points that go from the battery to various points on the frame; see that they are connected and tight.
- I may also do a continuity test from the negative on the battery to each of these points (looking for a break in the harness or indication that the chassis ground is not connected).
- A continuity test of the CB antenna ground to the battery (again, looking for a break or disconnected chassis ground).
- If I can't complete these checks because of access issues, then I will pull the fuse for the compressor (horn and heated grips) and see if the static goes away.
I think the BRP rep I have dealt with over the last several months must be on vacation, phone goes straight to voicemail (I recall my work phone used to do this when I set it for vacation). Anyway, I hope to have this all checked out as much as I can next week -- hubby is off his feet and can't ride or drive due to surgery on his right ankle).
All the best …. Ann
