You need a new igniton control, if it is bad your alternator wont charge your battery and you will be sad!!!,16400189//shopping/partTypeResultSet.htm

i have a 91 thunderbird and it took me days of testing to determine that the OEM ignition control is not built very well and will cause charging problems! go to auto zone buddy yeah!!

Dear annieek,
I have the same problem on my 91 Bird. I have checked with a friend that owns a repair shop. He says when you turn the switch on you need to have the Alt. light to come on before you start the car, if it does not come on (mine does not) it is a wiring problem. That light must come on before the car is started in order to "excite" the Alternator. I am in the process now of taking the dash apart to find the problem of why the light is not coming on. More info later. This may give you a starting point.

Why alternator don't charge on a 1979 ford thunderbird?

If you can use a new wire and they charge the battery then most likely you have a broken wire in the harness that runs between the alternator and the regulator.

When not running the engine for a week, the battery dies. When I jump start it, engine will start cranking very slow and pickup speed before it starts running.

it seems like the battery is going. clean battery terminals, also the grounding to the body (engine block, transmission, etc.) all should be shiny cleaned. suggest you go to autozone (or other auto parts) for a free battery & alternator tests.

My 94 5.4ltr. Thunderbird engine surges and my alternator gauge and headlights surge.But seems to charge the battery ok. Always starts.Only code i get says #7 misfire. Right bank coil pack.

Try replacing the wiring harness that connects to the top of the alternator. They vibrate and the wires inside break. They are only about twelve dollars.

It may be a bad alternator. After jump starting the engine and while idling, remove the negative terminal of the battery. Observe if the engine dies, then the alternator is bad.

Hi all, just about lost my hairr with this one. I have a 2001 7.3L, dual battery single alt set-up. I have replaced both batteries once, had them load tested a few times now, replaced the alternator...

Try to measure if there is a loss in the grounding harness between engine and body, and Batteries and body. By connecting a DVM from a good grounding point in body to either engine and battery neg terminal.
Try to "nail" the test probe to the lead terminal of the bat, in case there is a "contact resistance" between connector and terminal.

The alternator on my girlfriends 91 Chrysler Lebaron isnt producing enough power to recharge or keep my battery charged. its giving me the codes DTC41, DTC 35, AND DTC 31, now i know that one of those...

There are 2 types of alternators for this vehicle .code 41 is a field circuit code for the alternator The SBEC controlls the charging rate of the alternator . It could be wiring connections or the SBEC ( computer) to be the problem .You may have to back probe some terminals to find the problem ,but first check all of the engine grounds including the negative battery cables. The fault code for the field circuit is most likely generated because of an open circuit . The SBEC (computer) supplies the ground to energize the field circuit ..

Hope this helps

1979 Ford Thunderbird alternator not charging

Are the connections really dirty at the voltage regulator? These tend to get corrosion on them and cause weird charging system issues. Also make sure the ground is good on the regulator.

78 T Bird Not Charging. Have replaced alternator. Battery was charged off car.

did you inspect the + and - batt cables for damage? trace both cables esp the - to where it bolts to a ground. is your batt sealed, or are there caps that you can pry off to inspect the fluid level of each cell? use a batt electrolyte tester works sim to a cooant tester and check the strength of each cell. at first inspection of the batt cells, they should all be submerged in fluid. check the voltage of your batt with engine off and again with engine at idle.(if engine will start) around 12v (obviously) with engine off. start eng and recheck voltage-if it is higher say 13.0v or there abouts the alt. is working as it should. check your wiring harness for damage/corrosion/loose connections at the terminals. use a multimeter to check for voltage drops at various points. by what you have described it is probably a bad battery. checking for damage to batt housing/loose connections at the + - batt posts/corroded wires- pull batt cables off batt clean the posts w/a brush and baking soda solution, insert/turn a batt post cleaner over each post, apply a light coat of dielectric grease onto each post, connect the clamps to respective posts dont over-tighten so much that the terminal clamps get marred, but get them tight. good luck
