Yes, cables could also be the cause. The easy fix would be to just bypass the existing line from the alternator with a new cable. I just did that with my Sporty when I installed dual batteries. I just routed it along the fire wall... used a bigger gauge of wire too. I'd also consider replacing the ground cable at the same time. While your at it, look at the lead that runs from the positive battery terminal to the fuse box (attached to the factory cable). That's what connects the battery to the charging system, and vice versa. If you replace the pos and neg cables, you can probably salvage a good section of wire from from one of them to fab a heavy-duty lead to replace the stock piece. Just crimp on a few cable lugs and your set. Hope that helps...
