You'd have to open up the flash (I don't recommend) and replace it by soldiering a new one in place. If you can't make you're own contact or salvage/fit one from another source you must send it in for repair.

Make sure you using flash grade batteries and not rechargables. try energiser ultra or litiums or duracelll plus but nothing else. if the charge light is not coming up then most likely batteries. I would take it to your local camera shot and test your 7d with one of thier 430 just to make sure the hotshoe didnt short out the flashgun

What's your question? hi if the wire leading to the positive terminal of the battery gets corroded by battery acid can it effect the car in starting. ....

Most certainly. If battery acid is present on top of the battery, the seal between the post and the top of the battery is leaking. Replace your battery and use baking soda and water to clean the battery cable.

My car want start battery is fully charged. But the immobilizer light on the instrument panel stays on?

Having a full charged battery won't just solve the promblem. You might want to check with the battery terminal connection on the postive+ and negative-, It might be corroded, grease, or acid build up, so check for thse signs, also it could be that clamps are not fully tighten. You still can get power to the car from the baterry which in this case is leads to the immoblizer lights on the dash boards to stay on, but the terminal are corroded with acid, grease, or just from dirt, and with these element in presence, the battery is not fully ground. The engine needs a specific amount of amplitude from the battery for the engine to crank. A kia sorento v6 engine needs alot of cranking amp. So my solution is, check the battery connection terminal on the battery and the cable (positive and negative connections) de-tach the cable connections, clean the connection cables which are the adapter to the battery, and the battery terminals, with a toothbrush or high grit sandpaper until dirt, acid build up, grease are gone, and reinstall the cables. See if this will help.

2000 Honda VT 600 C Shadow backfires at low speed

Hi, Firewalke610 and the usual suspects are:
1. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead acid batteries.
2. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
3. Faulty main circuit breaker and or connections.
4. Faulty ignition coil and or connections.
5. Faulty spark plug, oil or gas fouled, wrong heat range or service type, wrong gap, loose in the cylinder head, broken electrode or insulator.
6. Faulty spark plug cables, leaking or broken, internal damage check for spark leakage in the dark.
7. Faulty ignition module, switch, CKP, MAP, CMP, sensor and or any connector in the ignition circuit could have corroded, loose, or broken pins/sockets
8. Burnt exhaust valve or air leak in the exhaust system.

Battarie termals corrosion

You mean a battery leaked acid and corroded the terminals?

Use some sandpaper to get the rust off. Also wipe them with a damp cloth with baking soda solution on the rag, to neutralize the acid before you use the sandpaper.

Clean up everything and use another rag and wipe wd40 (a little bit) on the terminals.

Have battery but engine wont turn over

1.Do the headlights come on? Are they as bright as they should be? No? Check the battery cables, and connections. A corroded battery cable terminal end, and battery terminal will cause this. (Even side post batteries have a terminal. It's just a flat area with a threaded hole) Side post batteries are notorious for acid leaking out of the side post area, and corroding the connections. (I change everyone of my vehicles to use a Top Post battery)

2.Battery terminals and battery terminal ends clean? Battery cables good? Then it's the starter solenoid, or the starter itself.

Inside the starter solenoid, (Mounted to the starter. It's that cylindrical looking object on top of the starter), are contacts. These can burn, and wear out over time.

Inside the starter are brushes. The starter is just an electrical motor. The brushes wear down over time, and do not make contact anymore.

If somehow this is the original starter, and starter solenoid, consider yourself LUCKY! It has seen it's use, and is well past time to be changed.

When I plug the battery in to be charged the light on the charge stays green. The light never changes to orange/amber. This is not a new battery I have had it for a while.

Your SLA (Seal Lead Acid) battery is must likely past its useful life due to Sulfation and internal mechanical damage (corroded plates): your charger, like for most car lead acid battery charger is indicating that only a very small charging current is flowing just like when a battery if fully charged ... or the terminals are not connected (no current)! You can check if the charger is working by preferrably using a multimeter or connecting a know good battery unit to the charger.

Powered in not On

That light brown liquid is acid leaking from inside the batteries. The same thing can happen with a flashlight or any other battery-powered object. Now you know why instructions for most battery-powered items always say to remove the batteries if the item is not going to be used for an extended period.

Unfortunately, your camera has probably been ruined by the battery acid. At the least, all or most of the battery contacts have been corroded, but they may possibly be salvaged by a competent camera technician. This problem is obviously not covered by any Canon warranty, although some battery companies offer to repair items damaged by their batteries under certain circumstances.

I suggest that you contact your Canon Service Center and describe the problem, then ask them to quote a price range for the repair. Once you have their price, take it to one or two local camera techs who have good reputations to see if you can get it repaired more cheaply. If the battery company offers any warranty to cover damages from their batteries (check a new battery package), then be sure to get a written report on that from Canon or the local camera tech and submit a claim to the battery company.
