When connecting to the car battery; Should the negative lead be connected to the negative or the engine block/frame of vehicle?

I connected mine directly on the battery but I'm sure either way would work fine.....make sure to connect the positive first (just a habit from jumper cables).....also remember that the instructions specifically say to plug in the unit AFTER it's connected (eg. don't connect it while it's powered up)!!!

I don't think it matters as long as you find a conductive part of the frame. I used the battery terminal.

Best to the negative post on the battery move the clip around for a good connection You'll love the tender

Those just show you what direction to plug in your battery. So the - Sign will always be the first pin where you attach the connector. It doesn't hurt anything if you plug it in upside down, it just wont work.

Most vehicles use a negative ground. In general, when servicing a battery, you should always disconnect the ground side first. That way, if your wrench slips and you hit part of the vehicle, you'll just be connecting the ground side of the battery to the ground of the vehicle, which causes no harm. If you slipped when loosening the positive post, and the ground was still connected, you could connect the positive terminal of the battery to the ground, which would cause arcing, or worse. So, because of that safety issue, people always disconnect the ground side first, and switches like this are usually placed on the ground side. Disconnecting either battery terminal will stop the battery from charging, since you no longer have a complete circuit through the battery. If you leave your RV plugged in constantly, and leave the battery connected continuously, be sure that your RV's battery charger is well regulated. (Although, perhaps that's why you wanted this switch in the first place-to prevent your charger from overcharging the RV battery.) Handy Bob's Blog, HandyBobSolar, has a big page of good information about RV battery charging. It's the page entitled "The RV Battery Charging Puzzle". I think I'm not allowed to insert links here, so you'll need to Google for it. Handy Bob says the biggest problem with typical RV converters is that some of them never get the batteries fully charged, even if left plugged in 24 hrs/day. Handy Bob goes on to suggest buying a large automotive battery charger, one that puts out 25 amps, and use that a few hours each day. That sounds like overcharging to me, but he's the authority here. Personally, I use a smart charger to top off my batteries, and I generally disconnect them from the vehicle before charging, and it's a low-amperage charger, as well. Mine's the 7 Amp NOCO Genius charger, and I think it's sufficient, but I'm only charging medium-sized batteries one at a time.

The manual basically reads: Wires that your attaching to the battery are crossed (AKA polarity)

The black wire connects to the battery or positive connection... The ground is obtained through the bolted connection of the jack base to the trailer tongue. Be sure that there is a good metal-to-metal connection when bolting the jack in place.

~~Connect the RED Lead to the Positive Battery Terminal and the Black Lead to the Car Frame, usually the Hood Catch above the Radiator. Switch on the Power Dome and Start your Car~~

The red wire connects to the center pin, the black wire to the outer ring. As far as polarity, it depends on what being plugged into it. If you want a pos. center pin connect the pos power lead to red. For a neg. center pin, connect the neg. power lead to the red wire.

Positive and negative from battery on one side; positive and negative to the 12v motor on the other side. There shd be very small print that illustrates which side is which

If it's a properly grounded, running vehicle, the battery ground should be solidly attached to the chassis. Therefor, attaching the inverter to bat + and any good chassis ground should be fine. But getting a set of those quick connect jumpers and using for the inverter rather than jumper cables would be ideal!

In my car I'm running a shunt between the alternator and the negative terminal to read the amps, the power was tapped from a cigarette lighter wire. I believe running the tiny power wires to the shunt would fry them when cranking.

Although not critical, most manufacturers highly recommend disconnecting the battery before removing/connecting MAF sensors. Failure to do so may introduce a spurious voltage spike into this sensitive device, thus maybe damaging/destroying it.

The two pieces are clamped together by the thumb screw to cause the connection. I use one on each of my antique autos and they operate great. I have also installed one on my stepson's car. He had a battery drain and that corrected that problem. It still has a problem but if he shuts it off every nightand then opens the switch, it will operate fine.

If the battery is positive ground, ground the positive lead from he pump. I have used similar pumps to fill the carb and then switched the electric off. The electric pumps through the mechanical pump and the mechanical pulls through the electric.

yes!,suggest you disconnect negative battery terminal during storage to preserve life of the car battery. charge jumper pack to 100% and connect cables. charge battery pack every other month to keep it ready to go

No, but it does not matter the red cable on one post from battery and the other one goes to the starter and the ignition wire plugs into the tab. Also a black ground wire is bolted to the mounting bracket of the solenoid. hope this answer your question.

Three things to check: 1. Do you really want the negative terminal on the left side of the battery? That's where it is on this particular one. 2. Check the battery configuration on your vehicle. The battery needs a different hold-down than the normal rectangular one. 3. Do you want a "post-type" hookup rather than a "screw-in" mount? This one is a "post-type".

There is a power cord coming out. They are 2 wires. The only hard part is there is no documentation as to positive vs negative lead. I tested both directions and chose which worked best.
