The cash-strapped Pilgrims have been served with a number of winding-up orders as they struggle to manage debts thought to be £9 million and although they have fought off these orders by selling numerous players they still need to find around £500,000 to ensure they are able to survive at least until the summer.
Ridsdale, who came in last month to look after the day-to-day running of Argyle, is becoming increasingly frustrated that majority shareholders Yasuaki Kagami and George Synan have yet to invest a promised six-figure sum and says he will quit the club on January, 31, when the transfer window closes, if the cash doesn't turn up.
He told the Plymouth Herald: "I am incredibly frustrated at what is happening. The survival hopes of Plymouth Argyle rest on this money coming in.
"I've given them an ultimatum that if it doesn't arrive within a certain deadline then I'm out of here. There is no politics here - the only agenda I have is saving the football club."
The sale of striker Bradley Wright-Phillips to Reading for £300,000 would have cleared some of the tax debt but the deal collapsed after the player failed a medical but he could still be sold with Rangers reported to be interested. Selling the naming rights of Home Park for advertising is another avenue the club is looking at which could bring in £500,000 a year.
