ezgo txt48 solenoid rattle

[demetriuscrisco]

Ok, I have a ezgo txt 48 golf cart that I'm trying 2 fix, when u press the gas pedal all you hear is a rattlING comming from the solenoid, I swapped the solenoid and the new one still rattles and the cart won't move... any suggestions?

Stop - the rattle is actually the contacts making and breaking the solenoid high amperage connection hundreds of times a minute because your voltage is too low to hold the magnetic field in.

Ok well I checked the be\eris and they all read around 8.3 and I connected to the post and negative cord from the cart and it reads 50.3.... where do I go from here?

[scottyb]

Connect black test lead to main negative on the battery pack and red lead to the battery side of the solenoid (at large post) Then try to go and see how far the pack drops.
You either have a battery problem or a solenoid activation circuit problem.

This morning the caet workwd for a luttle while and tjen stopped working again....Ok I did what u said when I connect to the battery pack with the key on, it reads 50.3 when I move the position lead to the solenoid it gives me 49.3..... what should I do from here?

[scottyb]

Look for a bad connection in the high amperage cables.... or the low amp activation circuit

[demetriuscrisco]

Is the low amp activation circuit the black thing that is connected to both posts on the solenoid?

Nope, that would be the resistor.. You need to put your meter on the two small posts on the solenoid and see what that voltage is when the key is on, in F and the pedal pressed.

It read 2.14 I checked the connection from the battery to the solenoid and from the solenoid to the black box (controller?) And they both were good

That should be 48 plus.. If I remember correctly, there should be a white wire with a yellow stripe plus a yellow wire on one small post and a blue wire on the other. Try the test again with the + lead of your meter on the yellow/white wire post and the - of your meter on the - main of the battery pack. Then put the - of your meter on the blue and the + on the + of the pack. See what those are.. I am thinking bad key switch..
