Troubleshooting 20 Amp Fuse Blowing on Demco SMI Stay N Play DUO  

Question:

Installed a Demco Stay and Play DUO Supplemental Braking System in my 2016 Jeep Wrangler. Power comes directly from Jeep battery post protected by a 20 amp blade fuse. During long downhills in mountains or in stop and go traffic the fuse blows. Ideas? Otherwise, very satisfied.

Helpful Expert Reply:

We've checked with Demco in the past for a similar problem and they suggested trying a 25 amp or 30 amp fuse and also to try making sure all of the grounds of the setup are good.
