Check your voltage regulator. (Most likely built into the alternator). When the regulators go, they pull voltage even when the vehicle is not being used. Two ways to check the regulator: Pull the alternator and take it to an auto parts store (most test for free). The other way (if you don't want to pull it) is to use an ammeter and see if it's drawing current while the ignition switch is in the off position. If there is current showing, the regulator is on it's way south. If you have an actual volt gauge in the truck, you may see it jump around or drop way down when you crank the engine. If so, that's a symptom of the regulator as well.

Hey Stephan P. and others... - 1994 Ford F-250, Turbo Diesel, pre Power Stroke - hard to start, maybe a minute or more?

Does it have dual batteries? A friend of mine threw 3k$ at his, then found out one of the batteries were low or had a bad cell. It was turning over for a long time, and we never suspected them being at fault. Like 2 750 or 850 CCA batteries. Have yours tested at a parts store to rule them out.

Where is the starter relay located

how long does it take to drain the battery? If the starter relay is bad, it will prevent the starter from spinning or will keep it spinning. There is something else draining you battery. Try removing fuses one by one or groups and see which circuit is draining you battery. If it is a "new" car, remember that they have a slight current draw even if all appears to off there will still be a slight current draw.

1986 ford f350 won't start

The solenoid click sounds very strong, implying that you have a charged battery and the ignition circuit is functioning out to the solenoid. Suspect an issue with the starter motor. Is the starter motor installed and connected properly?

New battery drains.

I can't imagine how changing the belt would have any effect on the electrical system if the alternator is working.
The way you check for a drain is to disconnect the battery ground cable and use a test light to make the connection between the battery and ground. If there is something drawing power from the battery the light will glow.
Then you pull each fuse from the fuse boxes until the light goes out. You also disconnect the starter and alternator if necessary.

My car wont start. I replaced my battery but it still wont start. Tested the alternator and it is good. Something might be draining the battery but not sure what?

Does the engine spin over and not start? Or turn the key and nothing happens?
New spark plugs and wires won't have anything to do with the starter and battery keeping the engine from spinning when you turn the key.
Need more specific explanation. Thanks,

This may not be a complete solution, but surely a place to start. Take the battery and get it tested. If it's fine, but the truck starts like the battery is dead... this is a great indicator that your starter is pulling WAY too much current. This could damage your battery, so replace the starter. Starters can also be removed and tested by your parts store before committing to a purchase. They are both easy enough to remove, you could take them both in and get lots of answers right away. If you have glowing wires, you should replace them as well as check all major wires from the battery to the starter, ground, starter relay, etc. before placing any new components in the system. Make sure your battery terminals are good and clean as well... this won't prevent shorts, but will be good maintenance while you're under the hood. Good luck!

My 2003 Renault Megane Scenic 1.9dci expression won't start

The funny sound you mentioned must be identified, could it be the starter trying badly to turn. Here the fault of your battery drain is that the glow plugs take a lot of current and it must NOT come ON when the starter motor runs. Hence the fault could be your GLOW plug relay unit with the auto cut off timer that is faulty. If you keep draining the battery to a lower threshold level , there is every possiblity that the battery life will be lowered . I hope the present battery rating is the recommended Amp/hr rating to give the extra run for the morning start. Next area of suspicion is the starter motor itself , it could have a bad commutator or a bush. It will be good to have a clean up and service. Finally check for excessive drain on your battery with a current check in series for the drain current when the switch if off. If the current exceeds the limit disconnect each circuit to confirm. hope this advice helps. good day

Here is a procedure to isolate a battery drain I found elsewhere and has already proved very useful several times.

Remove negative battery cable from the battery. Using a 12-volt test light, hook one end to the negative battery post the other end to the negative battery cable you just disconnected. The test light will glow or “light” if there is a drain. If the “light or glow” is faint, that is probably normal draw for the clock or computer. If the “light or glow” is bright, then there is a large drain. That should be corrected. Now start removing and replacing the fuses one by one until the light goes out; that one will be the circuit with the drain. ***Remember to hold in the button in the door jam for the interior lights.***
