185v to fan!

Geodesiq · 11-18-2010, 12:24 PM

While installing a charger I attached the pack charge wires to the fan by accident. Can I assume it's fried? Is there a way to test it? If necessary is there a generic substitute?

If you powered up the charger while connected, I would say the fan is fried....

The fan is easy to test just by connecting the proper wires.

If by miracle the fan still works....Don't relax yet....

The fan may be the least of your problems. Since it is tapped into the original fan wires, I would worry more about the controller that turns the fan on and off.....They tend to be expensive. I doubt Honda would have placed any protection into the fan circuitry to protect someone putting very high voltage across the fan.

You would need to see the fan work on its own (in its stock condition - no additional hardware attached) to know if everything is still ok. If you drive around with a blown fan control circuit, the fan will not come on when driving around if the batteries are getting warm and may overheat causing another problem.

Ron at hybrid battery repair may be able to help with replacement parts.

Perhaps a good idea for anyone else installing a charger is to apply power to the charger BEFORE hooking up the wires that you intend to connect to each area just to be sure you have the right wires (and polarity) by using a volt meter.

Also a good idea to anyone selling chargers to provide super clear instructions and require a waiver in case something like this happens.

In retrospect I think that should be standard operating procedure. I just assumed the wires were correctly oriented which they were not. Can I assume the IMA battery was not damaged from the 12v it was getting?

The actual battery pack should be fine with only 12v applied...Again it is the controller that I would be worried about.

I won't touch the rest of this with a ten foot insulated pole, but generic substitute? Absolutely. It's a 120mm, 12VDC fan. You could get a dinky one (better two, side by side) at a computer parts store. There's also lots of folks with spare Insight parts kicking around.

But if you have to ask, you might want to stop playing around under the IPU lid now.

I replaced the industrial fan(s) on both my packs with slimmer 120mm computer fans. They work fine, though you would want to check them fairly often to ensure they are still working fine.

I think the power to the fan is by the output contacts of a Relay, and DC fans usually have a diode in series with the fan motor which may have blocked the 185V

You might therefore be lucky and everything still continue to wotk.

However please consider your safety and consider hiring an electrician to complete the work of the charger install.

Thanks for the hopeful note. I'm seeing the holy one (Mike) on Mon for a MIMA install. Hopefully he'll get to the bottom of this.
