If the battery is good you will need to follow flow. Test light is the easiest to use. First hook light to ground and touch pos terminal,lights good next touch pos battery cable end, lights good. Next follow pos cable to starter pos terminal,lights good. Next hook test light to bat pos teminal,touch neg terminal,lights good. Then touch engine block, lights good ground. Next move test light clamp back to ground/neg side and touch alt pos terminal,lights good.if all that tests good, if all good move inside and check for power at ign switch pos term if at any time you dont find power you have wiring issue that needs to be addressed. Let me know what you find. Russ
Is this battery the type that has the removable tops? If so, check the water level in each cell. Use distilled water to fill the cells to appropriate levels. Be careful of over-flow. Battery acid is very corrosive. Other considerations; battery is being over-charged, battery is worn and will not hold a charge. Auto Zone and Advance Auto will check/test a battery for you.
The negative wires go to ground. Has there been add-ons to the electrical system? Clean the Pos and Neg terminals and cables.
Bad connection on cable ends or where they connect to battery. Quick check is if you have a good set of jumper cables, use the jumper cable as a replacement for what maybe the defective one. Hook negative cable good to battery neg. post and then put other side on neg cable to engine ground on block. See if it cranks, if it does than the trouble is on the neg. cable. If not then put positive cable on pos. post of battery. Then put other side of pos. cable on the starter post, try to start. If it cranks then the trouble is on the pos side of cable. Hope this helps.
if you have access to a digital multimeter, connect the meter (set to volts) across positive and neg. terminal of the battery, should read roughly 12.6 volts, close to 10 volts, battery may be going out, also test the alt output, disconnect neg term and place negative lead to battery neg post and positive lead to neg battery cable (make sure meter is set to amps) should read near the rating, if both those, then you'd want to do a resistance test, (set meter to Ohms) disconnect battery and connect meter neg to either pos cable terminal or where the pos cable connects to the alt and connect positive lead to opposite of neg, should read next to 0, the check resistance of the ground by connecting meter between batt neg cable and body of alt.
CHECK FOR FUSE lINK at BATTERY CABLE OR ON SIDEWALL OF ENG COMPARTMENT. ON THE Cable AFTER Starter Solinoid Check for Poor Connection there ---ALSO Your GROUND Connections will Cause this Be SURE of GOOD CLEAN CONNECTIONS at Both POS and NEG TERMINALS.
Positive of one battery to hot of vehicle wiring harness--neg. of that battery to positive of other battery--negative of that battery to block (ground)
you will need a 8 mm wrench or a 5/16 wrench to remove the side terminals on the battery. you must disconect the neg. first, then the pos.....when putting the new battery in , you must connect the pos. first, then the neg.
