Default Battery

I've been having some issues with starting my 74. I couldn't get it started on Wednesday but finally figured out that it wasn't in park but not until after I tried to jump it. Now, it's not starting again - it won't even try to start, behaving like it did when it wasn't in gear. My battery tender is showing that I'm at at least 80% charge. I'm wondering if I've managed to knock something loose trying to start it. I think everything in the battery box is as it was when I bought it a few weeks ago but I'm not absolutely certain.



The wire on the left is attached to the negative terminal. The hoses on the right go down through the bottom of the battery box to the right of the battery. Is this correct? Am I missing a connection somewhere?

Have you tried pushing the reset button on the unit in the engine bay, under the windshield ?

Default Neutral safety switch

Assuming your cables and connections are clean, I would bypass the neutral safety switch. Make sure the car is in neutral, with the parking brake set. Jerry

Yep. Reset the driver's seat belt interlock.

I'm not sure what you mean by the reset button. I'll have to look that up in my shop manual.

While looking for the button, I noticed that my battery tender is now indicating the battery charge is low and is charging. I'm wondering if the battery will actually take the charge.

It’s this little doofer, it resets the seatbelt safety system that can get it’s knickers in a twist.

Ah. My car's a bit of a Frankenstein - it's a 74 with a 70 LT-1 in it. I'm assuming this means that the button was bypassed:



I reseated that cable and tried to start it again - it attempted a very feeble start so I'm assuming it just doesn't have any juice. Now I have to figure out why the battery drained in the first place.

Ah right, yep looks like it. Only reason I mentioned it was when I took delivery of my 74, with a flat battery, that button needed resetting, fired straight up after.

That battery looks old, have it load tested,
Always start with a good, charged battery when doing electrical troubleshooting.

Your car should start in Park or neutral.
The neutral safety switch might need an adjustment.
The NSS switch is under the shifter cover.

Your starter interlock has been bypassed and not a problem if the jumper wire is making a good connection.

If your battery is too low a "Battery Tender" will not be able to charge it. They are not designed to do that.

You should put a regular battery charger on it and bring it up to full charge and as stated above, have it load tested. Most auto parts stores will load test for free. Make sure they use good load testing equipment.
