First check alt At The Back of Alt Big Red Wire Were hooks to Post (stud) Do you have voltage ?? How Much??
What Voltage do you have at same Place with Engine Running ??
Now At wires Were they plug into Alt ,Top. Wires in White Plastic Clip, Do You Have Powe With Key On ?? How Much Voltage??
Jump across the 2 in the clip (with Engine Running)ONLY TEMPORARY!! Do You Have Voltage at Battery ?? How Much??
If Over 13volts With Clip On (Jumped) You Need A Internal Voltage Regulator ..
Is Batt Light On on Dash ??? Theres A Lot Of Testing You Can Do !!! And I will Need More Infomation to Keep Going ... These are just some Possible Problems No Way In Depth ...

SOURCE: 2008 Ford F-250 Low beams do not work. High beams are fine.

just remove all the connections as it could be malfunction in the switches and the wirings needs to be rechecked to make it proper.other option could be bad dimmer switch. You will need to replace the turn signal/ dimmer switch as an assembly.to replace you will need to disable the air bag, drop the column, pull the wheel

SOURCE: Wiper fuse keeps blowing intermittently.

It looks like the wire circuit for the wiper motor is touching the car body when shaken so the only thing you can do is shake the wires and terminals yourself while engine is running then maybe you can pinpoint where the earthing is.

Why I don't have power to fuel pump fuse?

The power goes from the battery to the fuse box and then to the fuel pump relay, so just concentrate on the fuse box. Depends on vehicle and model whether fuse gets power anytime the battery is connected (hot at all times) or only when the key switch is in "on" (hot in run or start). You have a test light to check for power at the fuse terminals? That is how to start.
Some older models used "fusible links" in major circuits to distribute power, like to the fuse box, or to the ignition switch. The links act like fuses to protect wiring, they will "blow" or burn out if a big short or surge tries to damage wiring. Then you can just cut out and replace the fusible link. Nowadays, they mostly use maxi-fuses instead of fusible links, but you would need to consult a wiring diagram for your vehicle to really know the set up.

I have a 1996 ford e150 new alternator good battery but won't charge was charging but quit is there a fuse or relay

There are a couple of fusible links and a regulator fuse . G 60amp located in the underhood fuse box. Is the charge indicator lit on the instrument cluster ? The fusible links connect at the starter relay on righ inner fender . Do you know what a fusible link is and what it looks like ? New alternator ? aftermarket or ford replacement ? Check for B+ voltage at wires on the alternator , to see which have B+ voltage look at wiring diagram at http://www.bbbind.com/free_tsb.html Enter vehicle info. yr . make , model , engine etc... System click engine , then charging system under subsystem . Click search . then click blue link .

I have a 2004 chevy surban that keeps blowing the ignition fuse what can cause this

You have a direct short to ground on that power feed circuit . You need to find a power distribution diagram to see what all gets is power from that fuse . Isolate the circuits till the fuse doesn't blow any more , then trace out that circuit that blows the fuse .

Which Ignition fuse ? Which fuse box is it in ? under hood , passenger compartment ?
IGN A
40A
Ignition Switch RUN, START, RUN/START/ACCY
IGN B
40A
Ignition Switch RUN/ACC, RUN/START
Could be ignition switch problem , Chevy has had problems with them .

I purchased a 4 terminal starter solenoid. A 3 terminal was on truck. This 4 terminal solenoid includes an S and an I terminal. Is the I terminal used on a 1987 Ford Ranger 2.9 V6 4WD?

If the truck had a three terminal one on it then you would not use the (I) terminal, nor would it cause you to keep blowing your fusible link. It would cause a hard start cold because all the (I) terminal does is feed 12v directly to the coil on cranking. You have a short in the circuit that is on that fusible link. You need to get a wiring diagram and see what that circuit feeds. If the fuel pump isn't running than disconnect that circuit and see if it keeps the link from blowing. You may have to get a circuit breaker to install temporarily it to help find short. I have used a breaker and have gone directly to the fuse box and feed there to help isolate which circuit it is in. Good luck.

I have a 2004 Chevy trailblazer no start no crank but if I put key on hot wire the starter it will start I replace new ignition switch and new starter relay b

Before you do any thing check for loose or bad connections. Also check you ground connection to engine. Check Fuses, relay and for a Fusible Link open circuit. Now let me explain what a Fusible Link does. They are short lengths of small gauge wire installed between the Battery and the Ignition Switch, or the Battery and the Fuse Panel. They'll melt and open the circuit before damage occurs in the rest of the circuit. I hope this was helpful you.

2002 Pontiac Grand Prix GT wont start. Has new battery. Starter was taken off car and works. Relays and fuses are fine. Power cables cleaned. Driver information center dim. Headlights are on when key...

PNP park neutral safety switch . Try moving gear selector to neutral . If it starts the switch is bad .
Voltage drop test starter circuit .
fusible relay ??? Now thats funny ! It's just a relay , not fusible relay ! A fusible link is a kind of fuse ,will melt with a short circuit. TEST ,TEST DON'T GUESS and if you can't test ,take it to a qualified repair shop. How to voltage drop test starter motor circuit
Starter Voltage Drop
The computer has nothing to do with it .

http://www.bbbind.com/free_tsb.html Free wiring diagrams ! Suggest you view a wiring diagram to see what all is involved in the starter circuit . NO starter relay ! Enter vehicle info. under system click engine, then under subsystem click starting . You will when you turn the key to start it send's B+ voltage to the PNP switch ,from there it goes to the S terminal on the starter solenoid . Very simple . Get a volt meter an test B+ voltage .

I need a 1988 honda prelude under hood fuse diaphagram

The closest I got to a diagram was this, but it doesn't have the legend for each maxi fuse under the hood: REPLACEMENT
  1. Remove the fuse and relay box cover.
  2. Inspect the fusible links to determine which is faulty.
  3. Unplug and discard the fusible link. Fig. 1: The engine compartment relay box contains the maxi-fuses 93136p69.jpg

  4. Inspect the box terminals and clean if corroded. If any terminals are damaged, replace the terminals.
  5. Plug in a new fusible link of the same amperage rating. WARNING
    Never exceed the amperage rating of a blown maxi-fuse. If the replacement fuse also blows, check for a problem in the circuit(s).
  6. Check for proper operation of the affected circuit(s).

1988 Dodge Ram 150 318 V-8 Will not start. Battery good. Cables good.Starter is good. Put key in and Nothing. No clicks, nothing. Does this truck come with a spark igniter? Could this be the problem? Where...

Greetings!

Let's keep things simple to start with... Check the battery that it has sufficient charge. (I did say to keep it simple). Ensure the gear selector is in Park or Neutral if equipped with an automatic trans, or depress the clutch pedal if equipped with a manual trans.

Lastly, in keeping things simple... check all the fuses and fuse links (special fusible wire) that power is available to your vehicle's electrical system.

With a test light, check the starter relay with the key in start position is energising the starter relay... bypass the starter relay if no power is present. if the starter operates, you now know the problem is located within the start control circuit (from the key switch through the starter relay to ground via a neutral safety switch (auto) or clutch switch (Manual).

finding the fault should be quick with a circuit diagram.

Cheers, Jay
