"Why does my car amp not have power coming out of the speaker out put?"に関する回答speaker outputs won’t ever have any voltage on them. Speakers are rated in Ohms not voltage. I would take a multi meter and disconnect the speakers and read the ohm reading from the terminals of the speaker. they should be very close to the ohm reading on the magnet of the speaker. most likely 4 ohms or 8 ohms. If you get no reading from the speakers they are no longer working and would need to be replaced.
"Plug for power not working consistently"に関する回答Most likely, the power connector on the motherboard has cracked solder joints. You will need to find someone to reflow the solder for that connector OR the power connector has broken and will need to be replaced.
"Why is my heater not working"に関する回答Is the car overheating also? if not, most likely you have a stopped up heater core. You might be able to get it to work again for a while by flushing the heater core with a garden hose. Please be aware, do NOT do this when the car is warm/hot. You could burn yourself or damage your car if you do Most likely you have at least 4 hoses for the cooling system on the car. (you could have more) two going to the radiator, 2 going to the firewall. and maybe more going to the carburetor or throttle body. Find the 2 hoses going to the firewall and make sure the car is cold, Trace back the hoses from the firewall, remove the hoses from the non firewall end and then while disconnected take a garden hose on somewhat low pressure and run water in the hose and look at the water coming out of the other hose (if you put the hose end in a bucket, you can see the crap that is coming from the heater core) run water in to the heater core until you get clear water out of it and then put the garden hose in the other heater hose...
"How to set valves on a craftsman 17.5 riding mower"に関する回答1.) find out the settings for the valves. The Intake and exhaust valves most likely won’t be the same. 2.) get a feeler gauge set at any automotive parts store (a spark plug gap tool is not the same as a feeler gauge) 3.) get a flat screwdriver and a wrench that is the size of the lock nut on the valve adjustment 4.) Under most circumstances valves shouldn’t need to be adjusted. I would check for a bent push rod or a broken rocker arm. replace the push rod if it is bent. there is no way to use a bent push rod. 5.) take the wrench and loosen the lock nut on the valve adjuster, take feeler gauge and put it in between the top of the valve and the bottom of the valve adjustment screw. When it is adjusted correctly, the feeler gauge should have a slight drag when moved back and forth while in between the top of the valve and the bottom of the adjuster screw. (if you set the gap too big it could damage the engine). If the adjustment is right, hold the adjustment screw with the screwdriver and don’t let it move....
