Location: Chicago, Beverly | Check your ground connection for corrosion. If any corrosion or rust are present, disconnect it, take a file or sand paperand scrub the connector and where it connects pretty good, then reassemble. If you can find it at a store, coating your ground connection with "No-Ox" can help prevent or slow corrosion. Also, check your hitch ball, if real rusty this can sometimes cause a ground problem. A majority of lighting issues on boat trailers can usually be traced to your ground.. I have fixed several trailers already this year with basically a similar lighting problem. Almost forgot, sometimes your plugs can get some corrosion, I try and find pipe cleaners to clean out some of that corrosion.. a slim tip slotted screwdriver will sometimes work also |
