Saturn Ion I hooked the jumper cables up to my 2003 Ion to jump my other car. As I hooked up the horn started to blow and will not stop.....any suggestions as to what happened and HOW do I fix it ????

There should be a remote positive terminal under the hood in the engine compartment . Red cable an post on the junction box .It may have a red plastic cover over it. Hook the positive jumper cable there . The negative to a good unpainted metal ground on the engine .

In under hood fuse block fuse number 20 /10A check it
and check on the horn connector end if there is 12 V with lamp tester Check for a good round

Where did you hook up the jumper cables to the ion? I would start checking fuses. Hooking up the number cables in the wrong spot will blow fuses.

I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

Dead Battery

Connect both cables to the battery on the car jumping. Connect the positive lead to the battery and the negative to the frame or any metal ground other than the battery on the car being jumped.

Please see my tip at http://www.fixya.com/cars/r6222268-engine_doesnt_crank_turn_over . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.

Hi RH,

OK, The process is pretty straight forward, a second vehicle is traditionally assumed to be available.

Although those sidemount batteries can be a pain with the wrong type of cables.

So I'm guessing theres a wrench in the gears some where. You need to describe the problem in order to get it addressed.

Best regards
Mike

Get Jumper cables
Attach negative to negative
Attach positive to positive
Start car
Reverse lines 2 and 3

YOU DO.
Pull another car or battery to front of car ,,and get the set of jumper wires (RED/BLACK) Red lead goes to Poss term (the biggest one) on both cars ..
Then the black lead goes to the earth side of battery
When started let engine run for 2 minutes and then remove the Black lead first on both cars then the Red lead,then let it run for about another 6 minutes or take it for a drive ,,,but connect the leads around the correct way to batterys......

see if you can find the horn itself (often behind the grill) and test it by applying 12v and ground directly to the two terminals (you can use jumper wires to the battery terminals or a portable jump starter). if it blows it rules out the horn. if it doesn't it is the switch, fuse/relay or wiring.
