I do not understand what you are trying to state. Please provide more details about what you are trying to do and perhaps we can respond. I do know that you need to run the current thru the controller - both pos and neg in and pos and neg out.

Lift the ground = no double grounding - works on PWM and they did the circuit rather cheaply = so no I/O isolation, LEHenson at msn dot com Electronics Engineer

you probably have seen it at the Shorai site, but they have an application finder. What I mean is you input your vehicle and it finds the battery. That's how I did it and it worked great.

I just tried mine, and it worked fine. Be sure that the button end of each battery is against the flat contact, not the spring contact, and that they are in securely. Spin them in their slot. That fixes a lot of problems. I spent 30 minutes yesterday, trying to fix a toy we had found. I put new batteries in, to no avail. I took the entire electronics apart, even soldering on jumpers to bypass the circuit board. Nothing. Finally, I put a meter on the output of the battery box. No output!. I spun the batteries in their seats, and Voila! Also, the button end of the battery holder goes in first. Be sure the button contact on the battery holder springs back when you push it in. That's really all that can go wrong with it. Good luck!

the vehicle battery need too be conected ,jou have dan Always current.if jou have no current make use of e ohm divice,but dont use e ohm divice with current it will destroy your instument.this product is only for automotive.

I had the same problem the screw was stripped that held the battery so no connection. I returned it!

open up the battery box check the wires to see if they pulled loose , if they have pulled loose, reattach it should work. this is what happened to me.

The only cars it doesn't work on would be those without electric locks. If your doors don't unlock when the battery is disconnected---you've got electric locks.

I truly don't know the answer, but you could make a nut and bolt connection on both ends from the battery cables. Then it would work normally by just unscrewing the middle plastic knob. Only drawback might be that it wiggles.

Possibly have inadequate power source or wiring? Is this in a vehicle or being used as a base radio?

Well, that's why this needs to go to GARMIN direct for any & all issues. Not enough information to give a proper answer. BUT here are a few; DID THE GARMIN JUST NOT WORK, BEFORE YOU REPLACED THE BATTERY? NOW; try this, If you hook it in a cars cigaret lighter it gives a power source while charging the GARMIN see if that works. Remember this, very important, you can't leave a GARMIN or even a cell phone type device out in a car if its to HOT or to COLD // WHY, because it will cook the battery or freeze it will damage it. If you have a voltage tester type, test the battery voltage & or circuit. Could be a bad switch to. GOOD LUCK. Take care.

problems yet..only will go off if someone cuts the cables to your battery..you can get a volt tester to check if uncertain..

Check your installation, and look if you have something different according instructions, verify the isolator ground conectios.With the engine off, turn on vehicle lights, start accesories or devices, if the blue light doesnt dissappear, probably is not working

Probably need new sensor. Make sure you turn off power to system and disconnect back up battery before putting new sensor to use. Then can repower.

I am not sure but could test it for you. Are you able to have it installed so it's connected to the battery of the car? If you want to me to email you the results I can.

I'm guessing the plug in your connector is round, this one is oval with 8 holes connection. If oval and connection work, I don't see, why not Word of caution! if you don't unplug from battery when charging it will burn out circuit board. Mine did!! sorry couldn't be more help! charging

I had the same problem, couldn't get it to work from my Jeep's cigarette lighter. Finally cut the connector off and soldered on some alligator clips, and clip it right to the battery. That works.

It must be broken - if you put new batteries in, should work. Contact seller.
