Icom M33 Problem

Post by Balgarvie » Tue Jun 02, 2009 8:49 pm

I put my ICOM onto charge the other night, and after a minute or so the wee light on the charging unit started to flash. I left it the whole night, the light was still flashing in the morning but the radio hasn't recharged.
I've gone through the manual but it doesn't mention this at all.
Has anyone encountered this before and if so what was the solution ?
Thanks
B

Hmm - had somethign similar with a Garmin and it turned out to be a knackered battery, but then I'd left it charging for a few days and it didn't have a cut out. I do recall someone posting here that he'd once fully discahrged an ICOM battery and that had killed it. You'll have tried checking the charging contacts I guess so might be worth giving ICOM a call - a repalcement is about £55 - - -

I had a similar issue with ICOM M71 and was given this advice by the dealer:

This is an undocumented error code indicating either the terminals are dirty or the battery is defective.

I cleaned the terminals with a bit of fine wire wool which resolved problem

I had the same with an M71 a couple of days ago and think that it was down to the charger or the battery being too hot. The sun had moved round onto it, 30 minutes in the shade and it charged itself perfectly. Pity the manual says nothing about orange flashing at all, I just guessed that it might be the temperature.

Thanks everyone, it could well be the terminals so I'll give them a buff and see what happens.

Hi before attacking the terminals with wire wool use a hard pencil rubber. It is abrasive enough to clean the terminals without removing the plating. then a quick wipe with meths.

If that fails then you have little to loose with wire wool but make sure you dont short out the terminals as believe it or not wire wool will actually catch fire.

I bought an Icom M33 earlier this summer (distress purchase after another radio packed up), and subsequently bought a spare battery. The centre terminal on both batteries corroded away completely, after only 1 week of use at sea (and, yes, I was rinsing the radio in fresh water each evening). The loss of the centre terminal causes the flashing light described above, and also causes the unit to get stuck in the charging cradle, but doesn't seem to harm the set's charging or operation.
(Apologies to Icom: I haven't confronted them with this yet, and I usually like to give the manufacturer a chance before going public.)

I'm afraid after trying everything here to no avail I gave up on it. Theres a special adapter you can get which takes AAA batteries and that seems to work fine.

This is a battery condition associated with Lithium batteries. Send it to Icom and they will repair it with a special adaptor. It will typically be 8.2 v versus the best 8.5 volts. These batteries do not like being left doing nothing. Your charger is designed to pick up and report the fault with that specific flashing. Sometimes diconnecting the battery and charging it seperated from the radio will resolve other types of problem. £55 is steep.

Same problem here.

I just followed the advice on this page, cleaned the terminals, and hey presto - problem solved.

No need for a new battery, and no need to trouble Icom. I’m delighted.

Thanks folks
