Battery Relocation

90Stang · April 15th, 2007, 10:00 PM

ok i relocated the battery to the back and now my car seems like it has a hard time turning over and sometimes it wont turn over. should i just put a better battery in it. also do i need to run the wire from the alternator directly to the battery or can it just stay on the soleniod under the hood.

check your battery voltage and CCAs with a tester .Also make sure your
ground is tight and makes a good connection

its not a solenoid either it is a regulator. i had problems with mine thats the only way i know.

also make sure you engine has a good ground by getting your ohm metter out and making sure that from the bellhousing to the chassis has zero ohms or that the sound indicator beeps. Good luck bud

i think my battery needs to be bigger. because it only does it when the car is warm and someone told me that when the starter is hot it will take more to turn it over. if the car is cold it starts right up.

Could be the starter too. When a starter is getting weak, it will be hard to start or not start at all when it gets warm. Also depends on the type of headers you have. If they are really close to the starter, they could be transferring excess heat to the starter causing it to seem like its dying when its hot.

The voltage regulator on the Mustang is built into the alternator. The device on the firewall that the battery + lead attaches to is the solenoid.

In my opinion..

If this just started to happen when you moved the battery, it may be a combination of things. Typically when a car is hard to start when hot, it is the starter. Your starter may have been this way for a while but when you moved the battery, the extra length of cable reaching to the front may be a little to much for the battery to start the hard to turn hot starter ( in technical terms, the extra length of wire looses more voltage causing the starter to see less voltage which means it will not turn as easy). Basically, making the problem of a weak hot starter worse. I think you need to check three things, the first two being a free check. The battery and the wiring to the front. The battery can be checked at Autozone or similar for free and you can check your electrical connections to the front. If both of those are good then it is the starter. I had the same hard to start issue on my Mustang. I thought it was heat because of the headers and I through it was the battery. I turned out to be the starter. I paid $50 for a rebuilt one from Joe Blows local auto store and have not had a problem since.

Usually when that happens its the starter thats the prob..

then whats the external solenoids function off the alternator?

nolife · April 16th, 2007, 01:12 AM

The solenoid is a big switch to give power to the starter when you start the car. A solenoid would never be physically attached to the alternator. It is also used as a tie point for the other things that need a connection to the positive side of the battery, that is what all the other connections are that are attached to the same lug on the solenoid that the + battery terminal is attached to. I do not have my book in front of my but the little wire on the top middle (blue with red stripe I think) is the signal from the ignition switch that goes through the clutch safety switch to trigger the solenoid to shut and give power to the starter. I think I saw that you had an 84, it may be a different setup. You may be thinking about a solenoid that is attached directly to the starter, a lot of GM's have that design but Ford keeps it seperate and on the fender well.

It has no purpose, take it off, you don't need it at all.
