Question about 1972 Chevrolet Corvette

1 Answer

Electrical issue. , 1972 Corvette. Last fall the car had a short (don't know why), blew the fuseable link at the starter and the battery lost at least one cell. I've replaced the battery and link. I can get power at the starter solenoid (verified with a screwdriver across the terminals), but I have no power at the fusebox. Nothing works, lights, ignition, etc. Is there another fuseable link I should be looking for? Any other ideas?

Mike I believe these older cars have a power jump block.Some are mounted on the firewall some on fenderwell.I think this might be your power problem.

SOURCE: entire 1996 blazer electrical dies when starter solenoid engaged

if voltage reulator on alt. does not stop current after battery is charged it will over charge battery abd can drain cell from boiling electrolite out.check 4 bulged battery case(swelling) indication of overchaeging.the start problem could be your starter wires connection.remove starter wires clean contacts and torque respectively.dont forget the ground to motor.sounds like a loose or corroded contact somewhere.

SOURCE: 1981 Corvette will not start

The neutral safety switch is located in the shifter housing.

Here is a link to a good article on this topic, that would beat an explanation from me.

Yes, it sounds like the NSS is the culprit.

New starter and battery, and no power on a 2003 Toyota Corolla


I am not familer with this exact car but 2 things to look for, Many of the Jap cars have a main fuses. usually located near the battery, ina small fues box there will be a wire that attaches to the positive batt cable that goes to this little fues box It usually powers the IGN circut which powers the starting circut. .. on Americsan cars they use a fuseable link which is a piece of wire that burns out when a live positive wire is shorted out. in place of burning the whole wiring harness. its easy to see this problem since the wire will be burnet in half..

Being that this happened tells me that you have a short probably at or near the starter.that is blowing the fuse or burning the fuseable link. Look for this short or it will just burn out the fuse again.

Electrical short?


Not a short.
Either the circuit to the battery light is bad, or the fuseable link on the starter solenoid is toast. There is a 30 amp fuse in addition to the fuseable link, plus a 15 amp fuse on the circuit for the battery light.
All of these circuits need to be tested.

Blowing fuseable links from starter to alt, (well one) the gage is smaller then the OEM, however would a bad starter cause this fuseable link to fail, as the altenater is brand new


If this link runs from the alternator to the starter then i would say it likely but i belive the connection is to recarge the battery, the link that runs from the alt to starter connects to starter with another cable that runs to battery, so this link is used to charge the battery, heres a wiring diagram to show you. i would say its morelikely that the problem may be a bad alternator or the wiring from alt to starter is shorting. follow the wire (fuseable link) from alternator to starter and check it for shorting onto something, if nothing found then iwould say its the alternator or starter. to make sure which is the problem, when the link pops can you start the car, will starter spin over the engine if the answer is yes then replace the starter but if the starter doesnt spin engine with blown link then replace the starter, here are the wiring diagram to help.johnjohn2_148.gifjohnjohn2_149.gif

I have a 1985 Corvette. The battery was dead and I had the charger on it. I went to start the car with the charger on it. There is a wire that runs off the positive side of the battery and into the harness...


The fuseable link that is on it should protect the vehicles electrical at three places one for ignition switch a second for starter control and third for charging control ,The one on the positve is for the charging system

Replaced A 60am Fuse ,Ran For Two Days. Car Died and now i have no electrial juice to the whole car. suspect fuseable link.


You may be correct about the fusible link. Replacing a blown fuse without finding and repairing the reason it blew only leads to more problems and possible severe damage to wiring harnesses. Fuses are NEVER the CAUSE of an electrical problem. Blown fuses are ALWAYS the RESULT of an electrical problem. I would recommend taking the vehicle to someone who has access to the wiring diagrams and the proper equipment necessary to repair your electrical system. A blown 60 Amp fuse is nothing to play with. That fuse gave up it's life to stop your vehicle from burning to the ground. Please don't make it die in vain...car fires are never pretty!

I have a 1977 Corvette, L48, automatic, Dead elctrical system


It is more than likely in a fuseable Link coming off of the battery or off of the alternator causing your power lose. How many grounds did you check, because there are at least two grounds on the car. The first one is the main ground off of battery and the second one coming off of the back of the engine.

Lost all power all of a sudden 1977 corvette


do you know what fuse links are,and what they look like? usually down at the starter,the 2 or 3 hot wires besides the main battery cable all connect they feed the power to the fuse box,ignition and accessories,they have black square rubber blocks on them usually 3 or 4 inches from the starter they are built in fuses in the wires themselves check continuity throught them,if you already know about them ,the head light switch and the ignition switch are the first place i would look ,especially if they are original
