What happens if you put battery cables on wrong?

What happens if you put battery cables on wrong?

When the jumper cables are incorrectly connected, the polarity of the electrical system on the vehicle with the dead battery will be reversed for a few seconds. This can irreparably damage many of the sensitive electronic components that are common on today’s vehicles, such as on-board computers and electronic sensors.

What happens if I hook a battery charger up backwards?

A battery can explode when the cables are hooked up backwards. Anyone standing near the battery when it explodes could be seriously injured. Battery explosions can cause burns, permanent disfiguration and blindness.

What happens when one battery is connected with reverse polarity in a series of batteries?

Connecting a Battery to the Charger with Reverse Polarity In short, It may partially or fully damage the charger circuit. It may discharge the battery with spark or permanently damage the battery.

What would cause a car battery to reverse polarity?

Reverse Polarity Battery Reverse polarity can occur when the terminals and the cables are incorrectly connected. When polarity is reversed the current is going in the wrong direction. During this situation, if anyone touches the device, it can cause electrical shocks or it can damage the device.

Why is reversed polarity bad?

Why Is Reverse Polarity Dangerous? When an outlet is wired in reverse, the hot wire is now on the supposed neutral side. So, if you were to plug in the same lamp as noted above, the lamp socket would have power even if the switch was off since the switch is only on the hot side.

What should I do if my Toyota Sienna battery drains?

Battery always can recharge itself after I run the van for 1/2 hour. I tested the current drain last night between the cable and the negative terminal when the car was turned off: 0.001 Amps. Any suggestions? i would take the battery back for a replacement.

What should battery voltage be in Toyota Sienna?

First thing I would check is the alternator. With the engine off, see what the voltage is on the battery terminals. It should be a little above 12 V. Then turn the engine on and running, check the voltage again. It should be a little over 13 V, but under 14 V.

Are there any recalls on the Toyota Sienna?

AFAIK (this is based on my memory of discussions at the old site), the JBL-problem/recall was for 2005 Siennas “only”…..and only a limited production range were affected. For 2004 & reportedly some 2005s, the “battery-saver” feature does not work how most reasonable people would think it should work.

Can you turn off the interior lights in a Toyota Sienna?

It ONLY works under a VERY NARROW set of circumstances, and even then it ONLY works for the 2 overhead map lights in the FRONT ROW ONLY. In reality, it is NOT something most owners can rely upon as a “safety net” to help them remember to turn off the interior lights.
