Im new to the forum and I just picked up an 84 944..The car seems to be solid all around,but has a few annoying problems..If anyone can help with any of these,Id appreciate it.

1.The car runs very quiet when all electrical accessories are off,,but once a load is put on(headlights,fan,ect)the car emmits this horrible high squeal sound from under the hood..Could it be a bad belt?Tensioner?just out of adjustment?I dont know,buts its very embarassing..
2.The horn doesnt work.The previous owner installed a MOMO steering wheel..I removed the center emblem on the wheel and the wire is connected and making contact when the button is pressed..Maybe a bad fuse?relay?I do hear a slight beep---beep---beep coming from under the dash when the car is running..Maybe telling me something is wrong??Again,no idea..Again,thanks for any info you guys can provide..
