Need more input before SWAG can continue. - How long ago was it last working fine? (day, week, Months?) - What is the condition of your batteries?(aka- test them with a meter) Need a reading on each battery and the complete pack. - When you have it plugged in to charge does it do anything different? (does the little charge icon on the dash appear?) - If you drop the brake handle with key off does it “Beeeeeeeep” - Main switch ON, Press on brake pedal. Do brake lights work? - What was the reason for installing the R4F charger? ---

installed r4f charger six moths ago because delta q was not charging has been working since i installed it there is no 12 volt working brake lights do not working 74.7 volts total pack each battery is 12.4volts there is nothing on the dash how do you remove the large round fuses could the F 15 fuse be blown ---

working fine 3 days ago have not been working on it no beeeeeeep dc to dc converter harness 28 volts from both white to neg, 28v from red to neg, 28v from black to neg,0 volts from green to neg not Shure where to check for 74v going into DQ ---

Thanks, This is much easier to read. This statement needs a bit more explanation. > dc to dc converter harness 28 volts from both white to neg, 28v from red to neg, 28v from black to neg,0 volts from green to neg Those numbers (if accurate) are a bit concerning(28v is quite high). You refer to a “neg” you are using for reference in your tests. What is that? - Frame(chassis Gnd)? Were you doing this with car harness plugged into the charger? Just to make sure we are all on the same page, let us review… Looking at the DC output cable from the DQ, probe from Black to Red directly. If you still have the Anderson connector cube/cluster attached, the green wire goes into the back of Blue connector. This is the enable wire that comes from the Key. Applying 12v on this wire should switch on the output of the white wire (ref Black wire). Not to be confused with the Input cable to the DQ. That is usually a bigger connection and bigger wires. Measure between the Red and Black (NOT FRAME) and hopefully you should have better than 72v. ![DQ DCI Connects](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/e/eb40dbce3868f21500ca30b156f441e37ac4ea22.jpeg) ![DQ-DCI Outputs](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/b/bd78d7b238a7e55c2b3885876bc157022b144d04.jpeg) **Knowing this-** - Do you still have 24v on the outputs if the DC Converter? - What do you have on the B+ Inputs of the QC? - Is your meter on the correct setting? (verify by taking a reading off a battery again) ---

this is a 2014-15 e2 plug from DQ has 5 pins if I use black as neg there is no voltage on any pin my original readings where neg battery to these pins if I applied 12 volts to black and red then plug it into its location do you think things would work ---

Too many suggestions at a time? - What do you have on the INPUT of the Charger? (The other black and red wires?) Do you have the green plug in the picture? ---

Do you have another set of red and black wires going into the DQ? Normally they are in a big green plug like I posted in the pic above. ---
