RoadPro Recent Questions, Troubleshooting Help & Support

I had the same problem today and I found out that is the battery itself causing the problem. It's actually the connection. So disconnect the battery and scratch the battery pins and connect them again. If you can dip them in soda water (no sugar in it!) that would be better.
This problem starts as the battery beggins to get old and combined with cold weather outside becaomes a receipe for disaster. Anyway, if you can't afford a new battery at the moment remove your battery from your car (but first try and drain it totally...leave a light on or something) and recharge it (fully) with the duralast (havbe the duralst plugget into a outlet). It will have your battery working for couple of weeks.

Since you say, it is a 12v DC portable Jump starter, the battery inside it is also a 12V battery. You need a 12V charger (eliminator, wall adaptor or whatever you may call it) Regarding current, it could be anything above 500 mA. Better if it is a 1A or 2A or even 3 A depending on the amount you are willing to spend. Now is the most important part. The polarity. I do not know it since i do not have this equipment. Most chances are that you will find (on the RoadPro) a circle and a dot (along with a +VE and -VE marked near it) around where you plug in the adaptor. For most equipments the outer circle is the -ve and the inner dot is the +ve. (unfortunately this could be reversed in some equipments) If you can find this notation on your RoadPro you are lucky. Just go to any electronic shop and buy an adaptor (12V) that matches this circle and dot notation. The same symbol representing polarity will be marked on the adaptor also. Else, you will need the assistance of someone who can check the continuity using a multimeter. This way you can find the polarity. It is pretty easy. Hope this helps.

there are no fuses to replace(other than a reset switch on the back) if you get no responce from the unit even when you charge it then the interal circut bord is fried. it will still deliver a charge to jump start until the battery dies. after that its trash because it is not recommened to charge the intermal battery with a standard battery charger it may explode since it is a sealed lead acid battery

It's most likely the valve core. Sometimes they get jammed up, especially if you put a brass valve core in a stem that's attached to a TPMS sensor. If the stem doesn't have a sensor in it, then you can remedy this problem fairly cheap (my shop charges $1 for just the stem, but $6 to have it put in). If it is a TPMS stem, then you'll probably have to replace the sensor (last one we had to replace cost $156).


Hope that helps! Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/cameron_463100ffd54b591d

it has grounded out on you inside of your converter,Replace it.

Need confirmation that the AC adaptor for Duralast jump start model BP-DLG is a 12volt 450ma. Is this correct or do I need something else?

Bad transformer

On top of headlight assembly there should be 2 small metal bars about the size of a pencil. Turn each one and lift both out. Then you should be able to pull entire headlamp assembly out and reach bulbs from rear.

Make sure the ground from inverter to frame is intact. Make sure the positive and negative connections are clean and tight. If this all checks out, disconnect power to the unit for 1 hour and let is reset. If it still shows a fault then you really need to send it back to the manufacture for repair.

Hi, usually after you drain the unit down it will take up to 4 hours for it to charge up 100%. but do not leave it on the charger all the time when not in use because this decreases battery life.
