No power to the starter - 1996 Volkswagen Jetta

The wiring for a 1500a Li jump starter should include the following components:1. A power source such as a battery, generator, or other power source.2. A power cable to connect the power source to the jump starter.3. A circuit breaker to protect against any over-current conditions.4. A relay to control the flow of electricity from the power source to the jump starter.5. A charging port for connecting the jumper cables to the jump starter.6. A set of jumper cables to make the connection between the power source and the jump starter.7. Safety features such as a fuse, circuit protection, and/or a safety switch to ensure that the jump starter is not damaged or over-powered.

Check for power to the starter solenoid with the key in the start position. Chances are you have no power signal to the starter. If you have power at the starter it is most likely a bad replacement starter. If there is no power you need to check the ignition switch for power out in the start position. If there is power there you need to check the starter relay

stock engine?
i did not decode that, at all.
has power? (what 12vdc power or engine power)
turn key it wont start but does it crank.??????? fast..
and lose power, what power is lost 12vdc power or engine runs but lost power?
the power is back what power? name something, specific,
like 12vdc power, starter power, engine power.
the starter wont work, i take that its silent?
or
starter spins but engine dont?
or starter clicks
or starter, is weak
or ???? try to be clear,

no engine stated.
no transmission.

if stick shift the clutch switch must work or the starter will be dead.
does that help
ever hot wire a starter, see this.

if engine will not crank, say that.
then say sounds. it makes if any.

Confirm power is availible at starter main power supply, step one , using mutl meter check for 12 volts at battery positive terminal , 2, check main voltage supply lead to starter from battery pos post , 12 volts present? yer check voltage supply lead from battery pos post to altenater , then to starter , 12 volts present, yes , check small wire to starter at starter for switched 12 volts present yes change stater after confirming suitable ground, no, trouble shoot ignition / starter switch in colume

It can be faulty starter or there is loose connection from battery to starter.The starter assembly gets power from battery.Check voltages at starter wires and see if you are getting 12 volts or not.If not then its no power issue due to low battery volt or no connection between battery to starter.

Thanks.

before i can go any further i have seen bad starter kill power to small wire, does not sound correct i know but it happens, remove the small wire from the starter and test it for power with key in the crank position.

if there is power at small wire when removed from starter then starter is bad. let me know the out come. good day

Starter Fuse? Possible failed ignition switch. Loose Cables on battery or starter. Starter not grounding properly. Bad starter Relay? Use Voltmeter check voltage going to main starter wire while someone cranks the motor if not power check power to starter relay while cranking if no power suspect ignition switch.

You may have a bad starter, the best to determine this is by testing for power at the starter,also the battery is new but is it still good and fully charged, you may what to make sure battery is fully charged first, then test starter with a test light, there are two connection at starter, one is a battery cable this has power at all times then the small wire,this should have power when key is held in the crank postion,have someone hold the key while you test. if theres power at both connections then starter is bad, heres a diagram to show you where to test starter.

First test for power at starter,if your getting power to starter then starter is bad, also check the batt cable going to starter at starter for corrsion at terminal,if that cable has power and the small wire gets power when key in the crank spot then starter is no good,

check connections on starter , the small feed should get power when you turn key to start/crank position, if no power to that check the outputs on the back of the switch /ignition barrel,
if power to starter, then check power to back off starter on large cable (goes direct to battery) if power to both, starter u/s
if power at switch but not at small power feed at starter, relay/fuse fault, or if fitted cut out switch
