Oversized Club cart solenoid

You might have gotten a bad solenoid or the incorrect voltage one. Its capacity won’t have anything to with the issues you were having. Glad it is working again.

Hmm a larger coil could require more current to actuate it. Not saying that is or isnt whats going on here but its possible.

Sw180 has a 14 watt rating on the coil if I read it right. Stock solenoid will be close to that.

The solenoid always activated on throttle, and the label states 48V 200A.
The problem is a reverse issue, so I'm leaning towards the half speed voltage circuit as the problem. I'm tempted to bypass that resistor, but it's hidden somewhere in that gray accordion channel. Also, sending full voltage to the reverse circuit is a safety issue.

Fyi.... swapping out the solenoid is no picnic. The easiest way is to remove the right rear wheel, and it's splash cowling, or prepare to engage in using some 4-letter words you never thought were in your vocabulary.

If it is the resistor that I think you are talking about it is in the throttle circuit. It has nothing to do with the solenoid or at least it shouldn’t. If you put your meter leads on the two small terminals of the solenoid and activate it the voltage should be the same for forward and reverse.

Right there should be a snubbed diode across the coil or 2 small terminals. the resistor goes across the 2 main terminals. It's job is to prevent arching when the solenoid is deactivated.

Yes, that makes sense. I'll test the Voltage across the activation circuit in both directions and see if there is a differential.

Correct to a point. The resistor on the solenoid is to prevent arcing on both activation and deactivation.

On the 2002 DS there is also a resistor in the reverse throttle circuit so it runs slower.

With the SW180, the symptoms in reverse vary. When I switch into reverse, sometimes I get nothing, sometimes it engages only when at the half throttle position, sometimes nothing unless I switch from rev then to fwd and back to rev. No solid symptoms.
But, I have none of these issues with the stock solenoid. So, I've ruled out the FNR switch. Go figure.

Update: For what it's worth

Pack Voltage 52.4

SW180 activation voltage in both directions = 50.5v
Stock = 51.2 both directions
